Investigation on gyrotropic effect of magnetically biased graphene sheet in rectangular waveguide

In this paper, the transmission and reflection characteristics of a rectangular waveguide loaded with a graphene sheet is investigated theoretically, where the graphene is biased with a static magnetic field and shows gyrotropy. According to the nonreciprocal S-parameters of the composite structure, significant coupling and conversion are observed among different guided modes. In order to clearly provide its physical laws, the influences of operating frequency, biased magnetic field and chemical potential of the graphene sheet are also explored carefully.
