Passive thermal radiation control based on thermochromic W-doped VO2 metasurfaces
Radiative cooling becomes a popular research topic targeting an energy efficient solution for thermal management. Vanadium dioxide (VO2), as a thermochromic material, is able to switch optical property between dielectric and metallic states depending on its temperature. We present a passive thermal management solution through a VO2 based metasurface. Through a novel ALD process, the fabricated VO2 metasurface on polyimide substratehas a room-temperature transition and a high infrared emissivity of ~0.4.

Abstract
Radiative cooling becomes a popular research topic targeting an energy efficient solution for thermal management. Vanadium dioxide (VO2), as a thermochromic material, is able to switch optical property between dielectric and metallic states depending on its temperature. We present a passive thermal management solution through a VO2 based metasurface. Through a novel ALD process, the fabricated VO2 metasurface on polyimide substratehas a room-temperature transition and a high infrared emissivity of ~0.4.
