Abstract
An innovative approach to design coated spheres with null or limited scattering is proposed. The method is based on a reformulation of the Mie scattering that allows to describe the sphere in terms of impedance and reflection coefficients between travelling spherical waves. The proposed approach leads to a straightforward physical interpretation of the scattering suppression phenomenon and provides a simple tool to design multilayered spheres transparent to the electromagnetic radiation at a given frequency.
