Abstract

In this paper, we present Mie coefficients of double-layered sphere and consider the scattering problem, including the topics on field distribution, electromagnetic cross section, extinction spectra as well as some potential peculiar properties arising from the presence of left-handed media. The formulation presented here can be easily generalized to cases of multiple-layered spheres.
