This paper introduces a novel, single-layer, low-profile, and multifunctional coding metasurface based on frequency and polarization multiplexing, which can achieve four-channel wavefront manipulation functions. Numerical and experimental results have demonstrated its capabilities, and its high-efficiency, low-profile, and multiple functions suggest potential applications in radar detections, satellite communications, and high integration of electromagnetic systems.
Driven by the increasing demands for high integrations and large information capacities, the low-profile and multifunctional coding metasurfaces have drawn much attention. Here, a novel, single-layer, low-profile, and multifunction coding metasurface based on frequency and polarization multiplexing is proposed. Numerical and experimental results demonstrate that the proposed coding metasurface can achieve the functions of four-channel wavefront manipulation including beam splitting, abnormal deflection, vortex beam generation, and radar cross section (RCS) reduction at two operating frequencies under both linearly orthogonally polarized wave excitations. Owing to the high-efficiency, low-profile, and multiple functions' characteristics, the proposed coding metasurface suggests potential applications in the fields of radar detections, satellite communications, and high integration of electromagnetic (EM) systems.
