The polarizability of an alternative sequence of isotropic and radially anisotropic multilayer sphere

In this article, the polarizability of a multilayer sphere thatconsists of an alternative sequence of layers of isotropic andspherically radially anisotropic (SRA) material has been in-vestigated. Within each SRA layer, components of the ten-sor permittivity have different values in radial and tangen-tial directions. The mathematical treatment for extractingelectrostatic polarizability has been formulated in terms ofscattered potentials. Obtained results have been used to de-scribe the behavior of a whole sphere as a function of num-ber of the isotropic and SRA alternating layers using a nu-merical approach.
