Graphene can be defined either as an infinitely thin material with an optical conductivity or as a thin layer with a finite thickness and an effective complex electrical permittivity. Layered medium Green's functions are calculated according to these two definitions for multilayered structures including a graphene layer. It is found that numerical methods show a good agreement especially in the far field. Moreover, finite thickness method requires significantly less computation time than the effective complex permittivity method. Thus, considering the computation time and accuracy, the finite thickness approach is a better alternative to analyze the electromagnetic wave propagation and scattering in multilayered media with a graphene layer. © 2013 Wiley Periodicals, Inc.
