▎ 摘　　要

NOVELTY - A tunable terahertz graphene metamaterial absorber, comprises a superimposed four-layer together, structure of patterned top layer of graphene metamaterial, a dielectric interlayer, a metal bottom layer, and a substrate, where the metal base layer is formed on the substrate, a medium intermediate layer is formed on the metal base layer, and a top layer of a graphene metamaterial is formed on the medium intermediate layer. USE - Tunable terahertz graphene metamaterial absorber. ADVANTAGE - The absorber realizes the flexible control of the absorption intensity, bandwidth and frequency.
