Briefs: Communications
Researchers at the University of Birmingham have developed a new type of high-performance “phase shifter” using a liquid gallium alloy — which varies the phase angle of microwave and millimeter-wave radio signals — for use in advanced phase array antenna systems.

Briefs: Lighting Technology
RMIT University’s Arnan Mitchell and University of Adelaide’s Dr. Andy Boes led an international team to review lithium niobate’s capabilities and potential applications in the journal Science. The team is working to make navigation systems that help rovers drive on the Moon — where GPS is unable to work — later this decade.

Briefs: Software
This new technology — developed by engineers at Delft University of Technology, Vrije Universiteit Amsterdam, and VSL, and which can achieve an accuracy of 10 centimeters — is important for the implementation of a range of location-based applications, such as automated vehicles, quantum communication, and next-generation mobile communication systems.

Briefs: RF & Microwave Electronics
Researchers have created a device that enables them to electronically steer and focus a beam of terahertz electromagnetic energy with extreme precision. This opens the door to high-resolution, real-time imaging devices that are hundredths the size of other radar systems and more robust than other optical systems.

Briefs: Energy
Wireless power transfer was recently demonstrated by MAPLE — Microwave Array for Power-transfer Low-orbit Experiment — one of three key technologies being tested by the Space Solar Power Demonstrator (SSPD-1), the first space-borne prototype from Caltech’s Space Solar Power Project (SSPP), which aims to harvest solar power in space and transmit it to the Earth’s surface.

Making Satellite, Ground Communication More Effective
Rensselaer Polytechnic Institute’s Moussa N’Gom has devised a method to make communications between satellites and the ground more effective — regardless of the weather.
Briefs: Electronics & Computers
Devices of all types are becoming more intelligent and may include native Ethernet. However, there are many opportunities where proven serial communications will remain the best choice for cost-effective communications.

Testing Smart Surfaces to Improve Wireless Communication
Researchers at UBC Okanagan are looking at ways to improve cell phone connectivity and localization abilities by examining “smart” surfaces that can bounce signals from a tower to customers to improve the link.

Exploiting Signals Broadcast by Multi-Constellation LEO Satellites
Researchers have developed an algorithm that can “eavesdrop” on any signal from a satellite and use it to locate any point on Earth, much like GPS. The study represents the first time an algorithm was able to exploit signals broadcast by multi-constellation low-Earth orbit satellites.
Briefs: Communications
Researchers have outlined a new optical communication protocol that exploits spatial patterns of light for multi-dimensional encoding in a manner that does not require the patterns to be recognized, thus overcoming the prior limitation of modal distortion in noisy channels.
