Summary:In this paper, an step by step efficient design procedure for designing a multilayer absorber using graphene thin films is presented. The absorber design is based on scattering parameters of plasmonic waves propagating on the surface of graphene layers. We have provided appropriate interpretations for designing different features of the absorber including graphene pattern and substrate material. We have also presented a multilayer graphene-based ultrawideband terahertz absorber that is designed using the proposed method. Presented absorber has perfect absorption over 2.7 THz and its central frequency is about 3 THz, which is an acceptable fractional bandwidth ultrawideband absorbers.
