High‐Efficiency Mutual Dual‐Band Asymmetric Transmission of Circularly Polarized Waves with Few‐Layer Anisotropic Metasurfaces

Abstract

Dual-band mutual asymmetric transmission for circularly polarized waves based on the proposed few-layer anisotropic metasurface that can realize opposite asymmetric transmission in two different wavebands in the near-infrared regime. The high efficiency of asymmetric transmission is attributed to multiple reflection and transmission interference in the metasurface, which has been well verified by wave-transfer matrix calculation.
