dc.description.abstractLight scattering by a subwavelength sphere exhibiting radially inhomogeneous permittivity is here presented. The theoretical foundations describing the scattering response are given in a simple manner and the concept of polarizability is generalized incorporating the inhomogeneity effects. Two illustrative examples are briefly discussed, i.e., a power-law and a Drude-like inhomogeneous profile, exposing the physical mechanisms of their scattering response. The presented results can open the path towards the implementation of graded-index subwavelength particles in modern nanoantenna applications.en
