Abstract

This paper describes guide-wave characteristics of graphene based waveguides. The model of graphene conductivity is derived at first. The guided wave and the characteristics of PEC-graphene and graphene-graphene waveguides are studies in details with boundary condition defined. The dispersion equation is then derived by solving the Maxwell´s equations. The propagation constant is shown with the transverse electric and magnetic modes obtained. It is found that the attenuation in the grpahene based waveguide is low and can be compared with conductor waveguide in the THz band. By applying the externally biased electric and magnetic fields, its propagation characteristics can be tuned.
