New Phase Shifter to Reduce Antenna Signal Loss

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.

Terahertz Energy Focused by Credit Card-Sized Device to Generate High-Resolution Images

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.

Ultra-Low-Power Underwater Communication Device

MIT researchers have demonstrated the first system for ultra-low-power underwater networking and communication, which can transmit signals across kilometer-scale distances. This technique uses about one-millionth the power that existing underwater communication methods use.
