摘要: In this article, a multiband reflective polarization converter (RPC) based on asymmetric L-shaped split-ring-resonators(ALSRR) metasurface is theoretically presented. The proposed RPC able to efficiently convert linearly polarized (LP) wave its cross-polarized at the four resonant frequencies, besides, it can LP circularly polarized(CP) other eight frequencies with high conversion ratio(PCR). Furthermore, specific elucidation of surface current distributions polarizer reveal underlying physical mechanism mutual electromagnetic couplings. novel takes favorable advantages more operation frequency bands for both linear and circular conversions, which indicating great potential applications in terahertz detectors, antennas, imaging communication systems.
