▎ 摘　　要

NOVELTY - Graphene-based linear dichroism-adjustable double-functional super-surface comprises a bottom reflecting metal layer (1), a middle polyimide medium layer (2), a top part patterned graphene layer (3), where each layer is jointed with each other, the transverse period and the longitudinal period of the bi-functional ultra-surface with adjustable linear dichrocism based on graphene are P, the bottom is made of gold as the substrate, the thickness is h1, greater than the skin depth of the incident wave, it can effectively prevent the transmission of the electromagnetic wave, the material of the middle medium polyimides is the dielectric constant is 3.5, and the thickness of h2, the patterning graphene is half a hexagon to cut the half circle. USE - Graphene-based linear dichroism-adjustable double-functional super-surface for imaging display, terahertz switch, optical calculation, biological detection and sensing fields. ADVANTAGE - The bi-functional super-surface has adjustable linear dichroism based on graphene. The super surface has simple structure, wide application range and convenient integration, belonging to the terahertz metamaterial field, which can be widely used for signal processing, optical calculation, tera hertz switch and other related directions.
