The electrostatic field of conducting bodies in multiple dielectric media
Abstract
A method for computing the electrostatic fields and the capacitance matrix for a multiconductor system in a multiple dielectric region is presented. The number of conductors and the number of dielectrics in this analysis are arbitrary. Some of the conductors may be of finite volume and others may be infinitesimally thin. The conductors can be either above a single ground plane or between two parallel ground planes. The formulation is obtained by using a freespace Green's function in conjunction with total charge on the conductortodielectric interfaces and polarization charge on the dielectrictodielectric interfaces. The solution is effected by the method of moments using triangular subdomains with piecewise constant expansion functions and point matching for testing. Computed results are given for some finitelength conducting lines, compared to previous results obtained by twodimensional analysis.
