▎ 摘　　要

NOVELTY - The device has a vanadium dioxide layer (101), a graphene layer (102), a dielectric layer (103), and a metal reflective layer (104). The dielectric layer is provided on an upper end of the metal reflective layer, and the graphene layer is provided on the upper end of the dielectric layer. A groove (105) is provided in the graphene layer, and the groove penetrates into the dielectric layer. The vanadium dioxide layer is provided at the upper end of the bottom of the groove. The dielectric layer is left between the vanadium dioxide layer and the graphene layer. The electromagnetic wave polarization conversion is performed by adjusting the Fermi level of the graphene layer to transform the function of the multifunctional device between a perfect absorber and a polarization converter. USE - Multifunctional device based on VO2 and graphene hybrid metamaterials. ADVANTAGE - The tunable absorption and electromagnetic polarization manipulation can be achieved by introducing temperature-change phase-change metamaterials for realizing new applications of ultra-thin mid-infrared devices. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the multifunctional device based on VO2 and graphene hybrid metamaterials.
