Abstract: Embodiments of the invention may present a full-duplex nonreciprocal-beam-steering transmissive phase-gradient meta-surface. The metasurface may comprise a conductor layer interposed between two dielectric layers. Each of the dielectric layers may comprise a plurality of unit-cells embedded therein. Each of the unit-cell may comprise phase shifters and antenna elements. The meta-surface may function such that when an electromagnetic wave is received at the surface of the metasurface, the metasurface may transmit a wave having a similar or identical frequency to the frequency of the received wave but to a different direction in space.

The metasurface comprises a conductor layer interposed between two dielectric layers. Each of the dielectric layers comprises a plurality of meta-atoms embedded therein. Each of the meta-atoms comprises phase shifters and antenna elements. The meta-surface functions such that when an electromagnetic wave is received at the surface of the metasurface, the metasurface transmits a wave having an identical frequency to the frequency of the received wave but to a different direction in space.
