In this paper, a broadband reconfigurable frequency-selective surface (FSS) in terahertz band based on different metal-insulator transition (MIT) temperature of vanadium dioxide (VO₂) is proposed. By using different MIT temperature of VO₂, the broadband reconfigurable design of the FSS is realized. The results show that the center frequency of the FSS is 2.15 THz and when the temperature is lower than 60℃, the relative bandwidth is 74.19%. When the temperature is between 60℃ and 72℃, the relative bandwidth is 55.59%. Above 72℃, the relative bandwidth is 33.78%. The FSS has broad application prospects in other emerging terahertz fields such as terahertz regulation and communication.
