Abstract

In this work, we proposed a switchable metasurface based on phase transmission material of vanadium dioxide (VO2) with metal and insulation mode. Simulation results demonstrated that the metasurface can switch perfectly at frequencies of 1.89 THz and 2.67 THz from two perfect absorbing peaks to a reflecting peak and a transmitting peak. When VO2 erves as metal mode, there were two absorption peaks of 99.93% and 99.92% respectively. When VO2 serves as insulation mode, the reflection and transmission magnitudes were 92.50% and 90.50% respectively. Simultaneously, the structure was insensitive to the incident angle from the simulation result. The proposed metasurface could therefore provide potential application prospects for the terahertz band switcher or sensor.
