▎ 摘　　要

We propose a wavelength-selective emitter using nanoslit graphene metasurface. The nanoslit graphene metasurface consists of a graphene sheet, metallic slit, and dielectric layer for tailoring radiative properties. The utilization of rigorous electromagnetic simulation clarifies the mechanisms of thermal radiation. The proposed emitter shows high emissivity and a broad peak wavelength shift because of the electromagnetic resonances of graphene. This study may facilitate the initial design of wavelength-selective emitters using graphene metasurfaces. (C) 2020 Elsevier Ltd. All rights reserved.
