Training artificial intelligence models is costly. Researchers estimate that training costs for the largest frontier models ...

Abstract: An artificial metalens manipulates the electromagnetic wavefront phase via deploying transmitted phase and amplitude of metasurfaces units, which exhibits excellent merits in beam steering ...

Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that ...

Abstract: Achieving high-efficiency beam-steerable low-profile mm-wave array antennas has become particularly relevant for the advancement of modern communication systems. A completely novel passive ...
