- A semi-analytical expression for the attenuation coefficient is shown.

A new calculation procedure for the attenuation coefficients of electromagnetic wave by a partially charged multilayered sphere is proposed. The procedure is based on the utilization of a prescription which relates the expansion coefficients of the electromagnetic fields in the n-layered zone to those for the core zone through an iterative process, and then directly applies the coated-sphere model to calculate the expansion coefficients of the scattering field, and the extinction cross section. This method can be used to calculate the scattering properties of any multilayer charged sphere.
