Infrared Metamaterial Absorber Shows Promise in Radiative Cooling

Facebook Twitter LinkedIn Email
JILIN CITY, China, Feb. 10, 2022 — Researchers from the State Key Laboratory of Applied Optics, Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) have proposed a broadband, polarization- and angle-insensitive metamaterial absorber (MA) that covers the longwave infrared (LWIR) band. The design supports radiative cooling applications, as well as infrared imaging and thermal detection. MAs that are based on subwavelength periodic patterns can achieve perfect absorption at any target wavelength, depending on the design of their geometric parameters. Because they are...Read full article
