A research team, led by the Nano Optics Group within the Department of Physics at UNIST has reported achieving all-vanadium dioxide (VO2) multifunctional metasurfaces, which perform as a transparent window in the broadband THz regime with variable DC conductivity of dynamic range over three decades and selective switchability of near-infrared (NIR) diffraction.
