▎ 摘　　要

NOVELTY - The window has a light window body provided with a patterned graphene layer, a transparent dielectric layer and a frequency selective surface layer. The patterned graphene layer and the frequency selective surface layer of an integrated phase change material are arranged on two sides of the transparent dielectric layer in a parallel manner. The light window body transmits a pass band to generate frequency shift when the phase change material is in a metal state. A grid mesh patch type frequency selection surface (72) and a grid mesh aperture type frequency selection surface (71) are connected with each other. A phase change material patch (73) is connected with the grid mesh aperture type frequency selection surface. The aperture unit is arranged on a metal film according to a two-dimensional array period. A patch type frequency selection surface is formed by the metal patch unit on a substrate according to the two-dimensional array period. USE - Phase change material and graphene based microwave transmission passband adjustable high transmittance light window. ADVANTAGE - The window is easy to realize high optical transparency, and reduces adjustable transmission passband and out-of-band suppression problem with high absorption and high transmission, and adjusts transmission passband with to-be-absorbed out-band suppression. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a phase change material and graphene based microwave transmission passband adjustable high transmittance light window.
