Dual-band asymmetric transmission and cross-polarization conversion of linearly polarized wave using multi-layered metamaterial

In this paper, we propose a multi-layered metamaterial that consists of three metallic layers and two dielectric spacer layers to realize efficient dual-band asymmetric transmission for linearly polarized wave. The simulated results show that the metamaterial can achieve broadband and high efficiency cross-polarization conversion in two separated bands for y-polarized wave. The proposed metamaterial may has great potential as a polarization manipulation device in sensor applications, antennas and related applications.
