Dielectric polarizability of a sphere with arbitrary anisotropy: comment.
Sihvola's observation [Sihvola, Opt. Lett. 19, 430 (1994)] of an analogy between various elements of the polarizability dyadics for anisotropic spheres and the polarizabilities of chiral spheres is critically examined. It is argued that this analogy is both physically and mathematically misconceived.
