▎ 摘　　要

NOVELTY - The metasurface has a MxN-H graphene metasurface units that exhibit a cross-polarized electromagnetic response state which is used to generate out-of-plane anomalous reflected beams with the same polarization as incident wave, when a non-zero Fermi level is applied to a first rectangular graphene patch (3) on the remaining MxN-H graphene metasurface units contained in the graphene metasurface, and when the zero Fermi level is applied to a second rectangular graphene patch (4) at the same time, where M greater than or equal to 2 and N greater than or equal to 2. The graphene metasurface units corresponding to H co-polarized electromagnetic response state and the graphene metasurface units corresponding to MxN-H cross-polarized electromagnetic response state are randomly or cross-distributed to form a checkerboard structure. USE - Checkerboard graphene metasurface for generating non-coplanar split beams used for electromagnetic wave beam separation field. ADVANTAGE - The metasurface can realize non-coplanar characteristic and intensity of the separated beam reconfigurable characteristic, and at the same time improve the polarization purity of separated beam. The chessboard-type graphene super-surface unit exhibits a cross polarization electromagnetic response state and generates different-surface abnormal reflected beams same with the incident wave polarization by applying zero Fermi energy level to the first rectangular graphene patch to generate homopolar abnormal surface abnormal reflected beam by applying non-zero Fermis energy level. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the checkerboard graphene metasurfac.
