▎ 摘　　要

NOVELTY - The converter has a super-surface unit (1) provided with a medium substrate (2), a resonant structure (3), a graphene layer (4) and a metal floor (5), where the resonant structure is printed on the medium substrate surface. A center part of the resonant structure and a center part of the super-surface unit are overlapped. The graphene layer on the medium substrate is fixed between upper and lower surfaces. The graphene layer realizes electromagnetic coupling between the resonant structure and the metal floor to adjust and control a dynamic incident electromagnetic wave polarization state. The resonant structure is provided with an inclined rectangular metal ring and a double- metal strip. USE - Graphene composite hyper- surface based electromagnetic wave adjustable polarization converter. ADVANTAGE - The converter realizes adjust and control of different polarization conversion, has simple adjustment method, and is used for terahertz communication and radar detection system. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene composite hyper- surface based electromagnetic wave adjustable polarization converter.
