Method of lines for analysis of plane wave scattering by periodic arrays of magnetically-biased graphene strips

Abstract In this paper, efficient analysis of the plane wave scattering by periodic arrays of magnetically-biased graphene strips (PAMGS) is performed using the semi-numerical, semi-analytical method of lines (MoL). In MoL, all but one independent variable is discretized to reduce a system of partia...
