▎ 摘 要
NOVELTY - The lens has a graphene ultra-surface layer and a metal substrate layer formed on a bias voltage device. The bias voltage device regulates Fermi energy between the graphene ultra-surface layer and the metal substrate layer. The graphene ultra-surface layer is formed with a hollow rectangular hole array. The rectangular hole array is distributed in a x- y plane. The rectangular hole array is fixed between two adjacent rectangular holes on two-dimensional axis, where rotation angle of a column rectangular hole along y axis direction is compared with the rotation angle of row rectangular hole along x-axis direction to realize focusing function of a reflecting circular polarized wave. USE - Graphene ultra-surface based reflective polarized planar lens for an artificial electromagnetic material and optical device. ADVANTAGE - The bias voltage device is connected to the graphene ultra-surface and the metal substrate layer to adjust Fermi energy between the graphene ultra-surface layer and the metal substrate layer so as to change conductivity of a graphene layer to realize dynamic graphene plane ultra-lens focusing performance. The lens realizes wide band focus, easy to control, improves transmission efficiency, adopts actual application scene, and ensures higher practicability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene ultra-surface based reflective polarized planar lens.
