摘要：

We numerically and theoretically investigate the optical anisotropy of ultra-Thin bilayer L-shaped metal metasurfaces separated by a 200-nm-Thick silicon dioxide (SiO2) substrate spacer. A broadband asymmetric transmission (AT) to forward and backward propagate electromagnetic waves can be acquired from linearly polarized waves. Additionally, narrowband cross-polarization conversion (CPC) can be realized by x linearly polarized electromagnetic illumination. The calculated results demonstrate that the full width at half maximum (FWHM) of AT is 9...
