摘要：

We propose a bandwidth reconfigurable spatial filter using frequency selective surfaces (FSS) combined with phase-change materials (PCMs), vanadium dioxide (VO2) for advanced terahertz (THz) applications. The FSS filter is simulated using sapphire as substrate and employs circular loops FSS with VO2 rings in between. Simulations of this filter show bandwidth difference in the frequency range of 0.4 - 0.75 THz. As a demonstration, we tested a reconfigurable FSS geometry and observed a 15% in bandwidth change as per design
