摘要：

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 degrees C, the relative bandwidth is 74.19%. When the temperature is between 60 degrees C and 72 degrees C, the relative bandwidth is 55.59%. Above 72 degrees C, the relative bandwidth is 33.78%. The FSS has broad application prospects in other emerging terahertz fields such as terahertz regulation and communication.
