Ultra-Wideband Asymmetric Transmission Based on Chiral Metamaterials
In this paper, we experimentally demonstrate an ultra-wideband chiral metasurface with asymmetric transmission characteristics. The measurement results show that in a broad frequency range of 6-18GHz, the metasurface allows cross-polarization transmission coefficient of above 0.8 in one direction, while suppressing the transmission below 0.3 in the other direction. The asymmetric transmission performance remains stable under oblique incidence within the angle range of $\pm 30^{\circ}$. Our design may find applications in polarization conversion, radar communication and other fields.
