We present a numerical approach for the solution of EM scattering from a dielectric cylinder partially covered with graphene. It is based on Fourier-Bessel expansions inside and outside the cylinder. We apply the ad-hoc boundary conditions in the presence of graphene but due to the singular nature of the electric field at the ends of graphene, we introduce auxiliary boundary conditions. The result is a very simple and very efficient method allowing the study of diffraction from such structures.

We present an accurate and simple semi analytical model for investigating the magneto-plasmonic response of a 1D subwavelength graphene strip grating under an external static magnetic field when the graphene is considered as an anisotropic layer with atomic thickness. It is based on an effective medium approach (EMA) and a rigorous phase correction. The proposed model is numerically validated and evaluated by comparing the results with those obtained from the PMM method and from methods published in the litterature.
