MIT researchers have developed a low-power scanning reflectarray antenna that improves anti-jamming satellite communications ...

Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite ...

Keeping satellite communications secure is becoming more important as space becomes increasingly crowded. Military and ...

DARPA's Radio Frequency Risk Reduction Deployment Demonstration (R3D2) is set for launch in late February to space-qualify a new type of membrane reflectarray antenna. The antenna, made of a ...

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, ...

Reflectarray antennas combine the low profile of phased arrays with the simple geometry of reflectors to steer microwave beams for satellite links. They are composed of an array of scattering elements ...
