Abstract

Light scattering by a subwavelength sphere exhibiting a radially inhomogeneous permittivity profile is considered here. A generalization of the polarizability for radially inhomogeneous sphere is given in terms of a so-called inhomogeneity factor. The special case of an inhomogeneous Drude profile unveils a series of scattering peculiarities, motivating further discussion for the implementation of spheres with graded-index plasmonic profiles.
