Theory of Perturbation of Electrostatic Field By A Coated Anisotropic Dielectric Sphere

Summary A boundary-value problem was formulated for perturbation of an electrostatic field by a coated dielectric sphere made two distinct linear anisotropic (LAD) materials. Specific affine transformations were employed to represent the electric potential inside core and coating in terms solutions Laplace equation. transition matrix found relate source exterior region. The formulation can be straightforwardly extended concentrically multilayered spheres several homogeneous LAD
