Electromagnetic scattering by multilayered chiral-media structures: a scattering-to-radiation transform

Abstract

A bridge between the radiation and scattering theories is established. In particular, the method of vector wave eigenfunction expansion is employed to derive electromagnetic scattered fields by multilayered chiral-media structures. In addition, the electromagnetic fields are formulated in terms of integrals consisting a volumetric current distribution and the dyadic Green's functions. The exactly same expression of the electromagnetic scattered fields are obtained by using the two methods in the cases of planar, cylindrical, and spherical scattering objects.
