Electric Fields in Dielectric Multi-Layers Calculated by Digital Computer

Abstract

The electric field of a point charge or a spherical conductor in three or more dielectric layers on a plane conductor is calculated ated by digital computer. That of a point charge is calculated by the method of images, and that of a spherical conductor by the charge simulation method in combination with the method of images. Numerical examples show that the potential, the field strength, and the flux density, all satisfy the boundary conditions with good accuracy. The method can be applied to fields of a line charge, a pillar conductor, and an electrode of body of revolution in the same circumstance.
