▎ 摘　　要

NOVELTY - The absorber has a first dielectric layer arranged on a side of a graphene layer. A second dielectric layer is arranged on another side of the graphene layer. A resonant cavity is formed between the dielectric layers. The first dielectric layer comprises a first dielectric ring and a first dielectric ring array. The first dielectric ring and the first dielectric ring array are arranged on a surface of the graphene layer. The second dielectric layer comprises a second dielectric ring and a second dielectric ring array. The second dielectric ring and the second dielectric ring array are arranged on another surface of the graphene layer. A medium ring comprises a single-layer medium ring. The medium ring is formed as a circular ring, an elliptical ring, a square ring, a rectangular ring or a polygonal ring. USE - Double-layer coupling medium ring periodic array integrated terahertz graphene absorber. ADVANTAGE - The absorber increases graphene layer surface electromagnetic wave absorption rate and improves absorption efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a double-layer coupling medium ring periodic array integrated terahertz graphene absorber.
