Abstract

In this paper, an absorber based on split square graphene is designed, which produces double absorption peaks at different polarization incidence. The absorption rates of x-polarized waves at 7.86 THz and 12.63THz are 97.9% and 91.2% respectively. The absorption rates of y-polarized waves at 6.30 THz and 10.52 THz are 94.1% and 93.2%.

The absorption rates of x-polarized waves at 7.86 THz and 12.63THz are 97.9% and 91.2% respectively. The absorption rates of y-polarized waves at 6.30 THz and 10.52 THz are 94.1% and 93.2%. The effect of Fermi level on the dual polarization absorptivity of graphene is discussed. Therefore, this work may have great reference value for terahertz sensing, selective spectral detection and other fields.
