Broadband dual-circular polarized coding metasurfaces and their powerful manipulation of differently circular
Abstract:
In this paper, a concept of dual-circular polarized coding metasurface is proposed. Different from previous coding metasurfaces, it has independent and broadband coding behaviors for two circular polarized incidences. By encoding the unit cells with designed coding matrices (both 1-bit and 2-bit matrices), anomalous reflection or diffusion can be realized for two circular polarizations independently. The simulated and measured results demonstrate the independently functional performance of the coding metasurface. By adjusting sizes of unit cells, this concept can also be applied in terahertz and optical frequency regimes.
