Analysis of long wavelength electromagnetic scattering by a magnetized cold plasma prolate spheroid

Electromagnetic Scattering by an Inhomogeneous Gyroelectric Sphere Using Volume Integral Equation and Orthogonal Dini-Type Basis Functions

“…Applications of gyroelectric spheres are found in the electromagnetic (EM) interaction with complex property media, like garnet spheres which exhibit gyrotropic permittivity tensors [4], hyperbolic metamaterials where a periodic dielectric-metal structure gives rise to gyroelectric properties [5], or in photonic crystals which are composed by gyroelectric spheres. EM scattering in anisotropic materials is a difficult problem that has been treated for a long time in the past, and recently through a variety of approximate methods [6][7][8]. A first approximation is the Rayleigh approximation [6], where the scattering process is supposed to take place within the context of the Laplace equation, i.e., the electric field in the vicinity of the scatterer is nearly irrotational.…”

The coupled dipole approximation [7] consists of modeling the scatterer as a group of points.…”
