  • Abstract
    We designed, fabricated and characterized a tunable metamaterial in the terahertz frequency range based on a hybrid topology composed of metallic cut-wires separated by vanadium dioxide (VO2) patterns. The 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.
