Efficient characterization of the electromagnetic-coupling of wire antennas- and graphene patches

In this contribution, the simulation of electromagnetic coupling of a wire antenna and graphene by means of standard electromagnetic simulators, has been carried out. Simulations are performed at microwave frequency, from DC up to 100GHz, where the electromagnetic response of graphene is almost flat. The actual simulated device is given by a resonating wire-antenna, made of a CNT of finite conductivity, perturbed by the close proximity of a graphene patch: many other choices were possible, but the present test resembles the interaction of a microscope-tip with graphene, and may have some interesting fallouts on the experimental side. All the simulations are performed, for comparison, by an independent tool, based on the method of moments.
