What goes in is not what comes out with a spatio-temporally modulated metasurface reflector. Electronically controlled 2-D reflector promises improved microwave communications, beam steering without moving pieces, and one-way microwave mirrors Our new reflectors offer lightweight, low-profile alternatives to conventional antennas. This is a potential boon for satellites, where minimizing weight and size is crucial. Abul Azad LOS ALAMOS, N.M. March 20, 2020-Researchers at Los Alamos National Laboratory are reinventing the mirror, at least for microwaves, potentially replacing the familiar 3-D dishes and microwave horns we see on rooftops and cell towers with flat panels that are compact, versatile, and better adapted for modern communication technologies. "Our new reflectors offer lightweight, low-profile alternatives to conventional antennas. This is a potential boon for satellites, where minimizing weight and size is crucial,” said Abul Azad, of the MPA-CINT group at Los Alamos National Laboratory. "The panels could be easily incorporated onto surfaces of buildings or terrestrial vehicles as well.
