#dearMoon Project!

Comments off 559 Views0

Japanese billionaire Yusaku Maezawa announced September 17, 2018  that he has chosen to go to the moon in 2023 — and bring six to eight artists along for the ride.

“I thought long and hard about how valuable it would be to become the first private passenger to go to the moon,” Maezawa said. “At the same time, I thought about how I can give back to the world and how this can contribute to world peace — this is my lifelong dream.” 

Maezawa announced a name for his new project, #dearMoon, and a website, dearMoon.earth, and said that, before the BFR’s launch in 2023, he would select six to eight artists to go with him to space. These people will hail from a variety of disciplines, potentially including painters, sculptors, photographers, musicians, film directors, fashion designers, architects and more, he said.

 

SpaceX CEO Elon Musk and Japanese entrepreneur Yusaku Maezawa, who has booked SpaceX's first private flight around the moon on a Big Falcon Rocket, meet the press during the mission's unveiling at the company's headquarters in Hawthorne, California on Sept. 17, 2018.

Maezawa is the founder of the Japanese online retailer Zozotown, and he’s a dedicated art collector; in 2016, he purchased $98 million worth of art in two New York auctions, according to a BBC report.

One of those pieces was by the artist Jean-Michel Basquiat, whom Maezawa discussed during the news conference: Basquiat died in 1988, but what could he have created had he seen Earth from space? While looking at one of Basquiat’s paintings, Maezawa said, he came upon the idea to inspire other top artists to bring a space view down to Earth. 

In the coming years, Maezawa will select the artists as SpaceX works to develop the BFR rocket and spaceship . Although Musk didn’t reveal the amount of money Maezawa is paying, he did confirm the amount would have a “nontrivial impact” on the BFR’s development. (Besides tourist trips around the moon, Musk hopes to use the BFR to someday carry settlers to the moon and Mars.)

“Luckily, we still have some time before 2023, so I hope to work very closely with the SpaceX team and to reach out to each artist personally,” Maezawa said. “By the way, if you should hear from me, please say ‘yes’ and accept my invitation — please don’t say ‘no’!”

Musk also revealed tonight that Maezawa is the person who previously booked a two-person, round-the-moon trip with SpaceX aboard the company’s Dragon capsule. That flight, which SpaceX announced in February 2017, was to launch atop the company’s Falcon Heavy rocket before the end of 2018. (Content credit by:Sarah Lewin, Space.com Associate Editor |

RF Systems Test Facility.

The facility enables us to fabricate, integrate, and test in anechoic chambers RF systems to ensure they will work well in the field.

Laboratory researchers operate a shock tube in an anechoic chamber to quantify blast-wave propagation effects as part of the Laboratory's traumatic brain injury and auditory health research.
 

Laboratory researchers operate a shock tube in an anechoic chamber to quantify blast-wave propagation effects as part of the Laboratory’s traumatic brain injury and auditory health research.

 

The facility includes six anechoic chambers, specially outfitted with microwave-absorbing material to suppress noise and provide isolation from external signals that could interfere with system measurements. The chambers allow for antenna, radar cross section, electromagnetic interference, and system tests and measurements over a wide frequency range.

An ultrawideband array antenna is tested in the compact range anechoic chamber.

The three largest chambers — the system test chamber, compact range, and large near-field scanner — can accommodate large, heavy objects by making use of an overhead crane or a rolling gantry with a crane to suspend objects in the chambers. The compact range is used for measuring antennas and radar cross section of targets. The large and small near-field scanner chambers are used primarily to test and calibrate phased array antennas containing hundreds or thousands of transmit and receive modules for electronic beam steering. The millimeter-wave chamber accommodates small feed antennas and arrays, while the tapered chamber features an ultrawideband dual-polarized feed for measuring antennas.The facility also houses a systems integration lab, where staff can work on systems before they are fully tested in the chambers. The facility’s rapid-prototyping machine shop has a variety of machining tools to fabricate antennas, target-mounting fixtures, and other mechanical pieces needed to assist in testing. The machine shop also has a high-bay area, allowing for a wide range of mechanical work to be performed on large systems.

In the large near-field scanner chamber, the full-scale Multifunction Phased Array Radar prototype undergoes beam pattern testing.

What Will the RF Industry Look Like in 10 Years?

From smartphones to satellite service, GPS and more, RF technology is a feature of modern life that is so ubiquitous that many of us simply take it for granted. 

Radio frequency engineering continues to help drive the world across many applications in both the public and private sectors.

But technology advances so fast, it’s sometimes hard to predict what the world will look like in just a few years.

It’s amazing how far we’ve come in such a short time, and there is no sign of the demand for advanced RF solutions slowing down. Private companies and governments  around the world are competing to have the latest in radio frequency innovation.

  • What will the RF industry look a decade from now?
  • How do we stay ahead of the curve?
  • How do we find vendors who see the writing on the wall and know where things are going?

Upcoming Trends and the Future of RF

As most of us know, the 5G revolution is one of…if not the BIGGEST change!

By 2027, it’s a safe bet that we can expect 5G networks to have been up and running for some time, and consumer expectations for mobile speed and performance will be radically higher than today. With more and more people embracing smartphones around the world, the demand for data will continue to rise, and legacy bandwidth ranges, which run below 6GHZ, will simply not be sufficient to meet this challenge. One of the first public tests of 5G yielded astonishing speeds of 10 gigabytes per second at up to 73GHz.

5G networks will play an integral part in speeding up wireless communications, perfecting virtual reality, and connecting millions of devices we use today. It will be the key to ushering in th“Internet of Things” , in which countless household products, handheld wireless-istock.jpgelectronics, wearable devices, robotics, sensors, self-driving vehicles and more will be connected through network speeds unheard of today.

This is part of what Alphabet, Inc., Executive Chairman Eric Schmidt meant when he claimed that the internet as we know it will “disappear”; it will become so omnipresent and integrated into all the devices we use, that we’ll barely recognize it as distinct from “real life”.

Advancement in radio frequency technology is the magic that is going to make this all happen.

 

 

Military, Aerospace & Satellite Applications

In a world of rapid technological advancement and political uncertainty, the need to keep a military edge is stronger than ever. In the near-term, global electronic warfare spending is expected to exceed $9.3 billion by 2022, and the demand for advancement in military RF and microwave tech will only increase.  

Huge Leaps Forward in “EW”

EW is the “use of electromagnetic (EM) and directed energy to control the electromagnetic spectrum, or attack the enemy”. Major defense contractors will incorporate more and more EW tech into their products in the decade to come. Lockheed-Martin, for example, features sophisticated EW abilities in their new F-35 fighter which allows it to jam enemy frequencies, suppress radar, and more.

Many of these new EW systems utilize gallium-nitride (GaN) devices to help meet their demanding power requirements, as well as low-noise amplifiers (LNA) and more.

Additionally, the use of unmanned vehicles on land, in the air and the sea will also increase, along with a need for sophisticated RF solutions to communicate with and control these machines on secure networks.

In both the military and the commercial sector, the need for advanced RF solutions for satellite communications (SATCOM) will also increase.

One particularly ambitious project requiring advanced RF engineering is the global Wi-Fi project from SpaceX, which will require over 4000 satellites in orbit to beam wireless internet down to people all over the world, using frequencies of 10-30ghz, in the Ku and Ka-band range- and that’s just one company!

The Bottom Line

The next ten years will see enormous growth and innovation in the industry. If you’re looking for high quality, frequency control solutions for your next project, we’d love to hear from you. (content excerpt, blog.bliley.com/rf-industry, 011017 by Bliley Technologies).

Pentagon is working on a radio wave device that stops a speeding car in its tracks!

Comments off 1841 Views0

Vehicular terrorism is on the rise, but technology under development by the U.S. Department of Defense could save lives by disabling a weaponized car before it ever reaches its target.

The Pentagon’s Joint Non-Lethal Weapons Program (JNLWD) is working on a device called a Radio Frequency Vehicle Stopper to address the prevalence of vehicle-based attacks targeting civilians, Defense One reports.Image result for the pentagon

To prevent this kind of violence and other kinds of vehicular attacks (an unauthorized car rushing behind a military security gate, for instance), the Pentagon’s Radio Frequency Vehicle Stopper points high-powered microwaves at a vehicle, disabling its electrical components via the engine control unit and making the engine stall out.

 

 

You can watch the technology in action in the Department of Defense video below.

As Defense One reports, the group is developing two versions of its technology, one with a 50-meter range small enough to fit in a truck bed and another larger version with a range of more than 100 meters designed to remain in place.

The latter would particularly be useful in the kind of open public spaces that lend themselves to violent vehicular attacks in popular urban areas like markets and shopping hubs.

This kind of technology is only becoming possible now due to breakthroughs in powering the concentrated beams emitted in these kind of notoriously energy-hungry weapons.

While vehicle-based attacks were once rarely observed outside of war-zones, they’ve occurred with increasing frequency in high-density urban areas and tourist destinations in recent years. As the attacks in Toronto, London, Nice and New York prove, the results are effortlessly deadly to unsuspecting pedestrians.

It’s unfortunate that such a device is necessary at all, but if they were to become readily available, these Radio Frequency Vehicle Stoppers could discourage the rising trend of vehicular attacks, protect victims when they do occur and help law enforcement obtain additional intelligence by apprehending suspects without resorting to lethal violence.

Here Comes the Sun! First Visit Began this Weekend.

Comments off 1499 Views0

NASA is going closer to the Sun than anyone has gone before!

Humanity’s first visit to a star began this weekend.

NASA’s Parker Solar Probe will explore the sun’s atmosphere in a mission that launched early Sunday. This is the agency’s first mission to the sun and its outermost atmosphere, the corona.

After being delayed on Saturday, the probe successfully launched at 3:31 a.m. ET Sunday from Cape Canaveral, Florida, on a United Launch Alliance Delta IV Heavy rocket, one of the world’s most powerful rockets.

 
Although the probe itself is about the size of a car, a powerful rocket is needed to escape Earth’s orbit, change direction and reach the sun.
 
The launch window was chosen because the probe will rely on Venus to help it achieve an orbit around the sun.
 
Six weeks after launch, the probe will encounter Venus’ gravity for the first time. It will be used to help slow the probe, like pulling on a handbrake, and orient the probe so it’s on a path to the sun.
 
“The launch energy to reach the Sun is 55 times that required to get to Mars, and two times that needed to get to Pluto,” Yanping Guo of the Johns Hopkins Applied Physics Laboratory, who designed the mission trajectory, said in a statement.
 
“During summer, Earth and the other planets in our solar system are in the most favorable alignment to allow us to get close to the Sun.”NASA is going closer to the Sun than anyone has gone before
 

Preparing for a journey to the sun

It’s not a journey that any human can make, so NASA is sending a fully autonomous probe closer to the sun than any spacecraft has ever reached.
 
The probe will have to withstand heat and radiation never previously experienced by any spacecraft, but the mission will also address questions that couldn’t be answered before. Understanding the sun in greater detail can also shed light on Earth and its place in the solar system, researchers said.
 
“We’ve been studying the Sun for decades, and now we’re finally going to go where the action is,” said Alex Young, solar scientist at NASA’s Goddard Space Flight Center, in a statement.
 
In order to reach an orbit around the sun, the Parker Solar Probe will take seven flybys of Venus that will essentially give a gravity assist, shrinking its orbit over the course of nearly seven years.
 
The probe will orbit within 3.9 million miles of the sun’s surface in 2024, closer to the star than Mercury. Although that sounds far, researchers equate this to the probe sitting on the 4-yard line of a football field and the sun being the end zone.
 
When closest to the sun, the 4½-inch-thick carbon-composite solar shields will have to withstand temperatures close to 2,500 degrees Fahrenheit. However, the inside of the spacecraft and its instruments will remain at a comfortable room temperature.

The All-Purpose N Connector!

Comments off 297 Views0

The Type N 50 ohm connector was designed in the 1940s for military systems operating below 5 GHz. One resource identifies the origin of the name as meaning “Navy”. Several other sources attribute it to Mr. Paul Neil, an RF engineer at Bell Labs.

The Type N uses an internal gasket to seal out the environment, and is hand tightened. There is an air gap between center and outer conductor.

In the 1960s, improvements pushed performance to 12 GHz and later to 18 GHz. .

Type-N connectors follow the military standard MIL-C-39012.  Even the best specialized Type-N connectors will begin to mode around 20 GHz, producing unpredictable results if used at that frequency or higher.

A 75 ohm version, with a reduced center pin is  available and in wide use by the cable-TV industry.

These are both economical and rugged, for these reasons you will find them in a wide range of industries and vast spectrum of applications.

Quantum Computing

Light the Way to Quantum Computing.

Comments off 4001 Views0

Since the 1980s, researchers have been chasing after the quantum computer. Such a computer, they believe, could transform the task of information processing by handling data in novel, unprecedented ways. Whereas current computers can only process bits that occupy one of two states (0 or 1), one promising implementation of the quantum computer would rely on arrays of atoms in quantum states, called qubits.
Thanks to the strange nature of the quantum realm, qubits can occupy both the 0 and 1 states simultaneously and can also be entangled with, and thus closely influenced by, one another. Researchers are just beginning to explore the potential processing power that these qubits could unlock.

 

Yet, the quantum computer has always remained just out of reach because of various fabrication difficulties. For example, researchers are able to manipulate only a small number of qubits — on a scale of tens — as opposed to the required thousands or millions.

“Across all the groups in the world that are working on quantum computing, no one has developed a way to control a very large number of qubits such that you can use them to perform an actual computation of interest,” said Jeremy Sage, a member of the technical staff in Lincoln Laboratory’s Quantum Information and Integrated Nanosystems Group. “We can’t yet do anything that is both practical and better than what a classical computer can do.”

 

Sage and John Chiaverini, a senior staff member in Sage’s group, lead a team that is pursuing scalability by merging photonic integrated circuits (PICs) with a quantum computing method based on charged atoms, or ions, trapped above the surface of a chip. In 2016, in collaboration with MIT, the team demonstrated that PICs could be used to effectively manipulate the quantum states of ions by performing quantum gates. A quantum gate is the quantum version of a logic gate, which processes information by producing output bits (or qubits) based on inputs and a simple set of logical rules. The Laboratory team’s most recent milestone represents a breakthrough in the precise delivery of light from lasers to the trapped ions by significantly extending the range of wavelengths over which the PICs operate.

 

“We use lasers to rip off electrons, cool the ions down, and perform quantum gates,” Sage said. These changes to the ions that the lasers bring about are what would power the quantum computer. The ions that the team chose to use for their research are strontium and calcium, which react to specific wavelengths of light. “It turns out we need about 12 different laser colors that range from the near-ultraviolet to the near-infrared,” Sage added.

At the moment, most researchers shine lasers through windows in vacuum chambers to

strike the ions, but this approach leaves a lot of room for error. While it’s possible to hit a few individual ions precisely, scaling to the millions introduces a high probability of hitting the wrong one.

 

“What we’re trying to do is deliver the light in a different way by integrating the required light-delivery optics into the chip itself,” Sage explained.

 

“Our PICs distribute the light from several input lasers to an array of trapped ions,” said Paul Juodawlkis, assistant leader of the Quantum Information and Integrated Nanosystems Group, who leads the integrated photonics projects at the Laboratory. “At each trapped-ion site, we use devices called vertical grating couplers to redirect the laser light out of the PIC and focus it on an individual trapped ion.”

The vertical grating couplers are periodic structures that shoot light up and out of the chip, directly aiming it at and focusing it on the trapped ion, ensuring accuracy and mitigating the risk of hitting nearby ions.
The vertical grating couplers are periodic structures that shoot light up and out of the chip, directly aiming it at and focusing it on the trapped ion, ensuring accuracy and mitigating the risk of hitting nearby ions.

 

Instead of shining lasers through windows, the Laboratory team uses an optical input that is plugged into the chip. The input sends the lasers through the chip to the ion of interest via paths called waveguides that are specific to each wavelength of light. When the light has reached the area on the chip that correlates with the targeted ion, it emerges through the vertical grating coupler out of the chip and triggers the ion to change states.

The PIC technology needed to create this type of chip is already used extensively in the world of tele- and data communications. Yet these PICs are traditionally made of silicon, which absorbs the wavelengths of light required to manipulate the ions rather than allowing them to propagate through the chip.

 

Therefore, the research team developed alternate materials: silicon nitride and alumina. This year, they demonstrated a low propagation loss, meaning a small diminishment of the light as it is sent through the chip to meet an ion, while delivering light across a wide spectrum, from the near ultraviolet to the near infrared. The team’s work is the first-ever successful demonstration of a low-loss integrated photonics platform with light delivery over such a spectrum.

“We also demonstrated that the [vertical] gratings do indeed work,” said Suraj Bramhavar, another researcher on the team. “We are now working on ways to make these gratings more efficient so that more of the light we inject into the waveguide will reach the ion.”

 

“I think the ion-trapping field outside of the Laboratory is paying very close attention to what we’re doing here,” Sage said. “We are one of the leaders in this effort.”The Laboratory is uniquely capable of realizing this chip because of its expertise in integrated photonics and quantum computing, and the fabrication capabilities of its Microelectronics Laboratory.

 

The research team will continue working on refining the chip design and fabrication process.”There are a number of challenges that need to be addressed before a large-scale, useful quantumcomputer can be realized,” Juodawlkis said. “Estimates of when useful quantum computing will be available range from 10 to 20 years. An increasing number of groups around the world are working to solve the scientific and engineering challenges, and good progress is being made.”(July 9, 2018,/www.ll.mit.edu, Anne McGovern | Technical Communications Group)
