摘要
En 中文
Reflection- and transmission-type metasurfaces have great potentials in wireless communications. In this letter, we propose an absorption-transmission-type multifunctional coding metasurface composed of an absorptive layer and a transmissive layer. For incident waves at different frequencies with different polarizations, the proposed coding metasurface can perform three different functions independently: wave absorption at low frequencies, vortex-wave generation for the x-polarized wave and beam deflection for the y-polarized wave at high frequencies. Both numerical and experimental results verify the excellent performance of low-frequency absorptions and high-frequency dual-polarization transmissions. This work provides a method for developing multifunctional and reconfigurable components for the wireless communications in the future.
