Abstract :
We designed and characterized a tunable metamaterial in the terahertz frequency domain (0.1-1 THz) based on an hybrid topology composed of metallic cut-wires separated by vanadium dioxide (VO2) patterns. The THz frequency response of the hybrid metamaterial is significantly changing as the VO2 material is performing a reversible thermally or electrically-driven metal-insulator transition which drastically modifies its electrical and optical properties.
