Electronically Controlled 2D Reflector Improves Microwave Communications

Researchers are reinventing the mirror, at least for microwaves, potentially replacing the familiar 3D dishes and microwave horns seen on rooftops and cell towers with flat panels that are compact, versatile, and better adapted for modern communication technologies. The new reflectors offer lightweight, low-profile alternatives to conventional antennas. The panels could be easily incorporated onto surfaces of buildings or terrestrial vehicles.
