▎ 摘　　要

NOVELTY - The Graphene metastructure material has an uppermost layer which is a negative structure in which an asymmetric ring is dug out on the surface of gold, and adopts a metal-graphene-dielectric three-layer structure. A lowest layer is a dielectric layer, and a middle layer is a graphene asymmetric open-resonant ring, and the graphene asymmetric open-resonant ring is located in the negative structure of the asymmetric ring. The structure of the metastructure material has two-dimensional chirality. The left and right ends of the ring structure on the graphene asymmetric open-resonance ring are provided with two openings, and the sizes of the two openings are different. USE - Graphene metastructure material with two channels and multiple information chirality tunable in mid-infrared band. ADVANTAGE - The graphene metastructure material has simple structure, which greatly reduces the difficulty of processing, and has broad application prospects. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the structural unit diagram of the designed graphene meta-material.
