 If the history of radar intrigues you, then
you will not want to miss this article titled "Radar:
The Silent Weapon of World War 2," from the October 1945 edition of
Radio News. There are a couple dozen photos of early radar equipment installations
on land, ships, and aircraft. Radar pioneers Dr. A. Hoyt Taylor, Chief Consultant
and Chief Coordinator of Electronics at Naval Research Laboratory, and Leo C. Young
are pictured reminiscing over the "scope" of radar's history beside the first radar
set at the Research Laboratory. In 1922, while experimenting with communications
equipment for the Navy, the two men made the initial discovery of distortion in
radio reception caused by the intrusion of objects between the transmitter and receiver.
Working from this discovery, they and a number of associates made great strides
forward into the vast sphere of scientific fields covered by the word "radar"
today. Do you see the name(s) of anyone you know? ...
 There is no shortage of vintage electronics
aficionados who love nothing more than to spend countless hours - and sometimes
dollars - restoring and preserving the memory of the products that appeared along
the evolutionary path leading to modern electronics. David Goodsell documented his
Heathkit EC−1 Analog Computer project on the Nuts &
Volts magazine website. He, as do many hobbyists, even stuffed the cardboard
cases of the original electrolytic capacitors with modern replacements in order
to retain the authentic look. Prices on eBay for some of the vintage equipment has
gotten pretty outrageous. He paid more than $400 for this example ...

 "Despite limited space within a single mobile
device, one group of researchers has identified a new dual antenna design that could
allow phones to access both LTE and 5G networks. With any transition between old
and new generations of technology, there are compatibility issues. The transition
to 5G wireless communication is no different. One hurdle to be overcome in this
transition involves incorporating, within a single phone, new antennas that can
support the millimeter wavelengths of signals on 5G networks alongside existing
antennas that support the longer wavelengths transmitted by LTE networks. In a new
proof-of-concept study ..."

 Each week, for the sake of all avid cruciverbalists
amongst us, I create a new
technology-themed crossword puzzle using only words from my custom-created lexicon
related to engineering, science, mathematics, chemistry, physics, astronomy, etc.
You will never find among the words names of politicians, mountain ranges, exotic
foods or plants, movie stars, or anything of the sort. You might, however, see someone
or something in the exclusion list who or that is directly related to this puzzle's
theme, such as Hedy Lamarr or the Bikini Atoll, respectively. Enjoy ...

 "Scientists at the Harvard A. Paulson School
of Engineering and Applied Sciences have created a new way to store light in an
integrated circuit. The integrated photonics platform also allows them to electronically
control the frequency of the light being stored. Scientists believe their new system could
have a vast array of applications including microwave photonics, photonic quantum
information processing, and optical signal processing, to name a few. Scientists
have long hoped to harness microwave signals for such work. Unfortunately, they
had always proven to interact far too weakly with electrons to prove effective.
That's what led scientists to try a different method, using lithium niobate. This
is a material with powerful electro-optic properties ..."
 "In the 1970s, at the height of the Cold
War, American military planners began to worry about the threat to U.S. warplanes
posed by new, radar-guided missile defenses in the Soviet Union and other nations.
In response, engineers at places like U.S. defense giant Lockheed Martin's famous
Skunk Works stepped up work on stealth technology that could shield aircraft from
the prying eyes of enemy radar. This advantage is now under threat. In November
2018, China Electronics Technology Group Corporation, China's biggest defense electronics
company, unveiled a prototype radar that it claims can detect stealth aircraft in
flight. The radar uses some of the exotic phenomena of
quantum physics to help reveal planes' locations ..."
 "To better protect the global electronics
and IT supply chain, the Defense Advanced Research Projects Agency is looking at
solutions that can track and authenticate computer hardware components as they are
manufactured, shipped and assembled around the globe.
Resold and recycled components degrade the reliability and security
of many systems used by the Defense Department. The Pentagon has known about the
problem for decades and in 2012 issued comprehensive guidance to DOD program and
procurement managers to crack down on the problem, with a particular emphasis on
electronic parts and components. However, the increasingly complex nature of the
global supply chain means that even primary government contractors have difficulty ..."
 "Researchers at Intel and UC Berkeley are
working on a new transistor technology based on
magnetoelectric and spin-orbit materials that offers several
advantages over CMOS. According to Ramamoorthy Ramesh, a UC Berkeley professor of
Materials Science and Engineering, projections show that the explosion of sensors
and computing devices that will constitute the Internet of Things (IoT) - numbering
perhaps in the billions - could lead to such an increase in energy demand that electronic
devices could comprise as much as 20% of all energy consumed. That's a drastic increase
compared with 4-5% today. And just that is enough to justify the search for a new,
more energy efficient computing architecture. However, a second challenge has to
do with computationally intensive ..."
 "Lockheed Martin and Penn State University have
developed an innovative antenna technology that is now under consideration for use
in next-gen GPS satellite payloads. They worked together to dramatically improve
the design of the conventional short
backfire antenna by significantly increasing its aperture efficiency
(gain), without affecting its rugged and compact design, nor increasing its weight.
This type of antenna was originally developed in the 1960s at the Air Force Research
Lab. Since then, it has been used in many ground, sea and space applications, perhaps
most notably in the communication between NASA and the Apollo spacecraft, and it
is still in use on terrestrial communication antenna towers today ..."
 "Researchers have created a field-effect
transistor using a single-crystal, 'paint-on' perovskite. Transistors, and the conductive
traces that connect them, are routinely created by the billions on the surface of
silicon wafers, which are later cut into the individual 'chips' that power our computers,
phones, watches, and countless other electronic gadgets. But few people think much
about how those silicon wafers are made in the first place. It's quite tricky. Very
pure sand (silicon dioxide) has to be melted, at which point a seed crystal of elemental
silicon is brought in contact with the melt, which slowly deposits silicon atoms
on the seed, ones that extend the seed's crystalline lattice ..."
 "Chinese officials on Friday released more
imagery from the Chang'e 4 mission, a robotic lander and rover exploring the far
side of the moon after a successful landing January 3. The imagery released Friday
included a new view of China's
Yutu 2 rover captured by a camera aboard the Chang'e 4 lander,
a panoramic vista of the austere lunar landscape, and a sped-up video showing the
spacecraft’s final descent to the moon from the view of the probe’s descent camera.
Chang'e 4 was set to enter a low-power sleep mode Sunday as the sun set on the landing
site in Von Karman crater, a bowl-shaped depression measuring around 110 miles in
diameter located in the southern hemisphere of the far side of the moon ..."
 "Looking to enhance accuracy, the concept
uses Earth-based cars sharing data and generating corrections. In a patent application
filed in 2017 and made public last month, Tesla describes a technology that it believes
will result in more accurate
GPS positioning. The proposed invention would increase positioning
accuracy via determining and applying offsets - corrections - in various ways and
sharing this information between vehicles. Tesla describes a system of matching
camera data with vision maps to detect the exact location of a vehicle. In essence,
the system involves using camera sensors on Tesla EVs to fine-tune the GPS data ..."
