Abstract

Terahertz frequency selective surfaces with tunable characteristics are presented. Vanadium dioxide patches and metallic resonators were used. Vanadium dioxide behaves as an insulator at low temperatures and as a metal at high temperatures with transition temperature of ~ 68°C. Single to dual polarized bandpass FSS structure at 0.5 THz and tunable bandpass FSS structure were realized. We measured extinction ratio of 25 dB for the polarizer and 31% shift in the resonance frequency for the FSS.
