Frequency-Band Reconfigurable Frequency-Selective Surface Based on Different Metal-Insulator Transition Temperature of VO2

In recent years, Frequency selective surface (FSS) has been widely used in ships, aircraft, radar and satellite communication, and the reconfigurable design of FSS mostly uses diodes to achieve its purpose. In this paper, a temperature change frequency reconfigurable FSS (TC-FSS) based on two kinds of vanadium dioxide (VO
2
) is proposed to increase the frequency band at different temperatures through metal-insulator transition (MIT) of VO
2
at different temperatures. The results show that by changing the state of VO
2
through adjusting temperature, the FSS changes from a single frequency of 26.77 GHz to three frequency bands of 10.95 GHz, 16.14 GHz and 27.22 GHz, and the reconfigurable design of frequency band is realized.
