Abstract
In this work, a novel procedure for the simulation of magnetically-biased graphene by means of standard simulators, is made available. To this aim, the similarity of graphene with lossy ferrite has been exploited. Simulations can be performed at microwave frequency, from DC up to 100 GHz, where the electromagnetic response of graphene is almost flat. The Duality theorem is applied to establish the formal equivalence of a thin layer of un-biased ferrite with biased graphene: boundary conditions and excitations are properly set in order to respect this equivalence. The simulation test-case is given by transmission/reflection of a plane-wave through a graphene sheet, with normal incidence. In order to validate the numerical results, simulations are performed also by independent analytical methodsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
