摘要：

Scattering characteristics of electromagnetic waves are analyzed by a uniformly charged coated sphere using the Lorenz -Mie theory. Numerical calculations are presented for charges on the surfaces of the interior core and exterior shell, respectively. When the surfaces are charged, the extinction efficiencies are affected by the radius ratio of the two layers and the surface potential. The scattering characteristics are further simplified to Rayleigh scattering using the Taylor expansion in a regime where scattering is significantly influenced by charges. The Rayleigh scattering in this regime can replace the analytical solution derived from the Lorenz-Mie theory. (c) 2021 Elsevier Ltd. All rights reserved.
