Descrição: In this paper, a new solution for electrical characteristics of electromagnetic scattering by a radially multilayered gyroelectric sphere is proposed. The spherical geometry is divided into N +1 regions (where N can be an arbitrary integer), and each layer is characterized by a scalar permeability and a gyrotropic permittivity tensor. Electromagnetic fields inside and outside the sphere are theoretically formulated based on the eigenfunction expansion technique in terms of vector spherical wave functions. Numerical calculations are subsequently performed using those derived formulas. The derived formulas and the developed source codes are partially verified by the good agreement between our numerical results of radar cross sections with those obtained by Geng using the Fourier transform method. After the validations, some new specific examples are further considered and their results are presented, so as to investigate specific characteristics of these electromagnetic scattering problems.
