Abstract :
A multilayer sphere with a fixed external radius and with an arbitrary number of layers, as a possible realization of a Radial Uniaxial (RU) sphere is presented. The well known quasi-static model for the polarizability of the multilayer sphere is considered. The limits in which the multilayer sphere can be considered a RU sphere are discussed. Moreover different techniques are shown for layering the spheres and it is found which of them is convenient in terms of convergence speed.
