▎ 摘　　要

NOVELTY - The device has a graphene-metal mixed layer (1) provided with a multi-layer graphene layer and a metal arm. The multilayer graphene layer is formed as a ring structure. Metal arms are arranged at an equal interval on a periphery of the multilayer graphene layer. Metal arms are connected with an inner side of the multi-layer graphene layer, where the graphene metal mixed layer and the metal frequency selective surface layer are made by laminating PVC on a copper foil. A printed laminated copper foil is etched in an aqueous nitric acid solution by using a printed toner as an etching mask. USE - Graphene-based transmission dynamic adjustable flexible frequency selective absorbing device. ADVANTAGE - The device realizes adjustable transmission on the pass band through the graphene sandwich structure, so that the frequency selective absorber have the function of continuous space energy manipulation, and realizes application prospects in compatibility and protection. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene-based transmission dynamic adjustable flexible frequency selective absorbing device.
