Paper Abstract

We present a tunable reflector based on VO2 thin films in the terahertz frequency range. The reflectance of the reflector in the terahertz region can be tuned by controlling electrical properties of VO2 thin films. The change of electrical properties of VO2 originates from an insulator-metal transition of VO2. The experimental results demonstrated the effectiveness of the tunable reflector in the terahertz region. The tunable reflector of the VO2 thin films is very suitable for terahertz systems.
