Abstract

This study proposes a reflective metasurface for full-duplex nonreciprocal-beam-steering and amplification. The metasurface is realized by leveraging the exotic characteristics of novel interconnected meta-atoms providing three main functions simultaneously, i.e., reception, non-reciprocal gradient-phase shifting, and transmission. Such a metasurface can provide directive and diverse radiation beams, and steerable beams by simply changing the bias of the gradient nonreciprocal phase shifters. The proposed structure provides large wave amplification, and is immune to undesired time harmonics, leading to a highly efficient beamsteering in the reflective state.
