NOVELTY - The utility model claims a based on graphene-metal hybrid super-surface multifunctional THz polarization converter. is composed of a graphene-metal mixed ultra-surface layer, silicon, silicon dioxide substrate layer medium substrate layer and metal floor layer. graphene-metal mixed ultra-surface layer is composed of multiple graphene and metal surface unit, these graphene are periodically arranged on the surface of the silicon dioxide substrate layer and metal-surface unit. each of the graphene and the graphene sheet by sheet metal and metal-surface unit. the metal sheet is butterfly-shaped, and the metal sheet at the same time about the surface transverse x-axis symmetry and surface longitudinal y-axis symmetry. The utility model can be adjusted by changing the loading bias voltage between the graphene-metal mixed silicon surface layer and the dielectric substrate layer to achieve the purpose of adjusting the graphene Fermi level so as to realize the deflection linear polarization and circular polarization conversion function of the multifunctional polarization converter main body of switch.
