Design of a Broadband Tunable Terahertz Absorber Based on Graphene
In this paper, an absorber for the terahertz band is designed. The structure is modeled and simulated using CST simulation software, and the absorption rate under different conditions is explored based on the absorption rate calculation formula. The results show that the model designed in this paper achieves an absorption rate of over $90 \%$ with a bandwidth of 1.25 THz under normal incidence conditions, with a central frequency of 1.845 THz.
