Abstract
Control of light absorption and transmission by metal-insulator-metal (MIM) metasurfaces are important for applications in optical windows. In this study we show realization of photo-thermal energy conversion for the radiative cooling.
By controlling absorption and transparency of MIM metasurfaces with thin metal substrate and Indium-Tin-Oxide (ITO) substrates, a high transparency at visible wavelengths and high absorption at mid-infrared wavelengths was realized for a prospective application in efficient cooling or heating of the room.
