A Dual-band and Dual-polarization Multiplexed Reflective Metasurface Unit Cell

In order to achieve more multiplexing degrees, a dual-band and dual-polarization comprehensive multiplexing method is proposed in this paper. On this basis, a single reflective metasurface based on a cross-shaped resonator is proposed and simulated. The experimental results show that the designed unit cell can independently control the x and y polarized waves of 10GHz and 17GHz respectively, effectively isolate the two frequencies, and realize dual-band and dual-polarization multiplexing.
