AN INTEGRAL-EQUATION METHOD FOR ELECTROSTATICS OF ANISOTROPIC COMPOSITES

An interface integral equation is presented for the electrostatic prob lem in a composite where the components have anisotropic conductivity tensors. The electric potential is represented by a single-layer charg e density on the component interfaces. In a simple numerical example i nvolving anisotropic discs, the charge density is expanded in a Fourie r series. The integral equation is then solved to high accuracy with a modest computational effort.
