▎ 摘　　要

NOVELTY - The absorber has a metal structural unit layer that is laid on a dielectric layer (6). The metal structure unit layer includes four H-shaped metal plates with the same specifications. The four types of H-shaped metal plates are respectively a first H-shaped metal plate (1), a second H-shaped metal plate (2), a third H-shaped metal plate (3), and a fourth H-shaped metal plate (5). The first H-shaped metal plateand the fourth H-shaped metal plate are arranged symmetrically up and down. The second H-shaped metal plate and the third H-shaped metal plate are arranged symmetrically. The first H-shaped metal plate and the fourth H-shaped metal plate are perpendicular to the laying direction of the second H-shaped metal plate and the third H-shaped metal plate. A linear graphene (4) is laid on the dielectric layer. One end of the linear graphene is connected to the second H-shaped metal plate and the other end of the linear graphene is connected to the third H-shaped metal plate. USE - Graphene-based terahertz wave absorber with adjustable polarization dependence. ADVANTAGE - The absorber obtains better absorption rate of the transverse electric (TE) wave in the terahertz wave band by adjusting the chemical potential of the graphene to control the absorption rate of the TE wave and transverse magnetic (TM) wave, and realizes voltage control of the absorption rate of the TM wave. DESCRIPTION OF DRAWING(S) - The drawing shows a top view of the graphene-based terahertz wave absorber with adjustable polarization dependence.
