A Dual-Polarization Transmission Response Switchable Frequency Selective Surface with Phase-Change Material

A Dual-Polarization transmission response Switchable frequency selective surface (FSS) with phase-change material (PCM) is proposed in this paper. The presented FSS is composed of wideband transmission layer and switching control layer. The wire gird in bottom layer with PCM provides the switchable feature. Simulation results show that the proposed FSS can achieve the transmission coefficient is 85.4% (0.68 dB) from 8 to 12 GHz when the structure is in the conduction state. When the FSS structure is in the off state, the transmission efficiency is 5.8% (12.4 dB) from 2 GHz to 18 GHz. In addition, the FSS structure can achieves good polarization stability.
