Abstract

Layered medium Green´s functions (LMGFs) are calculated for a multilayered medium including graphene-like atomically thin layered materials. A spectral integral method (SIM) implemented with LMGFs is used as an exact radiation boundary condition to truncate the computational domain in the finite element method (FEM) to form a hybrid SIM/FEM which is applicable to arbitrary inhomogeneous objects. Numerical studies confirm the accuracy of the method.
