▎ 摘　　要

NOVELTY - The absorber has three-layer structures that are divided as a periodic net graphene layer, a medium layer and a metal layer. The periodic net graphene layer measures lateral period and vertical period and is formed as sine and cosine, parabolic and elliptical shaped structures. The medium layer is specified as a silicon dioxide insulator. Thickness of the medium layer is measured. The metal layer is made of gold or a conductor. Thickness of the metal layer is compared with depth of an incident wave part. USE - Graphene-based terahertz band adjustable wave absorber. ADVANTAGE - The absorber is simple in structure, and has wide range of applications. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene-based terahertz band adjustable wave absorber.
