On the modeling of the self-polarizing field for a coating of point polarizable species on an isotropic dielectric sphere

Our previous model dealing with the optical properties of small uniformly coated spheres is used iteratively to give the effective polarizability for homogeneous isotropic dielectric spheres and compared with results predicted by the Lorentz expression. Better agreement with the Lorentz expression is obtained using a modification of the model used to evaluate the self-polarizing field for the coating.
