Popis: Due to the static magnetic field, the conductivity for graphene becomes a dispersive and anisotropic tensor, which complicates most modeling methodologies. In this communication, a novel equivalent circuit model is proposed for graphene with the magnetostatic bias based on the electric field integral equation. To characterize the anisotropic property of the biased graphene, the resistive part of the unit circuit is replaced by a resistor in series with current-controlled voltage sources (CCVSs). The CCVSs account for the off-diagonal parts of the surface conductivity tensor for the magnetized graphene. This proposed method is benchmarked with numerical examples. This communication also provides a new equivalent circuit model to deal with anisotropic materials.
