Ultra-wideband transparent 90° polarization conversion metasurfaces

We propose to realize ultra-wideband transparent 90° polarization conversion metasurfaces by combining multiple plasmon resonances and Fabry–Perot-like resonances. An ultra-wideband polarization conversion metasurface is designed using a double-head arrow structure and metal gratings. It has been demonstrated that the bandwidth can be broadened greatly based on multiple plasmon resonances, while the efficiency can be enhanced strongly based on Fabry–Perot-like resonances. The both simulated and measured results show that the bandwidth of cross-polarized transmission is very wide, with a 1:6 3 dB bandwidth. The experimental results agree well with simulation ones.
