The polarizability of an arbitrarily shaped electrically small particle of an isotropic dielectric material embedded in an isotropic dielectric host material given in a recent article [Opt. Eng. 52, 051205 (2013)] is incorrect. In particular, the polarizability cannot be a scalar (unless the particle is either spherical or cubical), but must be a dyadic.
