Equivalent circuit for VO{sub 2} phase change material film in reconfigurable frequency selective surfaces
- Department of Electrical and Computer Engineering, ElectroScience Laboratory, The Ohio State University, Columbus, Ohio 43212 (United States)
We developed equivalent circuits of phase change materials based on vanadium dioxide (VO{sub 2}) thin films. These circuits are used to model VO{sub 2} thin films for reconfigurable frequency selective surfaces (FSSs). This is important as it provides a way for designing complex structures. A reconfigurable FSS filter using VO{sub 2} ON/OFF switches is designed demonstrating −60 dB isolation between the states. This filter is used to provide the transmission and reflection responses of the FSS in the frequency range of 0.1–0.6 THz. The comparison between equivalent circuit and full-wave simulation shows excellent agreement.
