BeamsteeringBeamformingConformal metasurfaceConsiderable recent research interest has focused on the possibility of using metasurfaces for manipulation of terahertz wavefronts. For example, metasurfaces allow a beam to be targeted in any desired direction using strategically placed meta-elements. With rapid...
Terahertz (THz) beam steering as large as 120 degrees ($\\pm60^\\circ$) is demonstrated in a broad frequency range (1.2 to 1.9 THz) by changing the Fermi levels of different graphene resonators accordingly. This metasurface can provide a new platform for effectively manipulating THz waves....
In this paper, a phase gradient metasurface (PGM) composed of unit cells having the capability of high-efficiency linear polarization conversion for the transmitted wave has been proposed to achieve ultra-wideband high-efficiency beam steering. It has been found that high-efficiency anomalous ...

Over the past years, metasurfaces have been of great interest due to their ability manipulate optical wavefront by introducing a phase gradient across the transverse directions of the wave. This phase gradient was usually realized using plasmonic resonat
The demonstrated meta-broadcasting communication system merges optical wireless broadcasting communications and metasurfaces, which reduces the complexity of beam-steering devices while significantly increasing their performance, opening up a new avenue for high-quality optical wireless broadcasting communications....
