Three-dimensional nonreciprocal beamsteering-amplifying coding metasurface
Three-dimensional nonreciprocal beamsteering-amplifying coding metasurface
In this research, we present an innovative approach to achieving three-dimensional nonreciprocal-beam-steering, signal coding, and amplification using a reflective metasurface. Our proposed metasurface exploits the unique characteristics of interconnected supercells to simultaneously perform three key functions: reception, coding, and non-reciprocal gradient-phase shifting for efficient amplification and transmission. By capitalizing on the inherent properties of the novel supercell arrangement, our metasurface facilitates directive and diverse radiation beams, with the added capability of steering beams through simple adjustments in the bias of the gradient nonreciprocal phase shifters. The structure not only ensures significant wave amplification but also exhibits immunity to undesired time harmonics, resulting in highly efficient beamsteering in the reflective state. This study represents a significant advancement in the development of metasurfaces with multifunctional capabilities for next-generation communication systems and signal processing applications.

Abstract
In this research, we present an innovative approach to achieving three-dimensional nonreciprocal-beam-steering, signal coding, and amplification using a reflective metasurface. Our proposed metasurface exploits the unique characteristics of interconnected supercells to simultaneously perform three key functions: reception, coding, and non-reciprocal gradient-phase shifting for efficient amplification and transmission. By capitalizing on the inherent properties of the novel supercell arrangement, our metasurface facilitates directive and diverse radiation beams, with the added capability of steering beams through simple adjustments in the bias of the gradient nonreciprocal phase shifters. The structure not only ensures significant wave amplification but also exhibits immunity to undesired time harmonics, resulting in highly efficient beamsteering in the reflective state. This study represents a significant advancement in the development of metasurfaces with multifunctional capabilities for next-generation communication systems and signal processing applications.
