Moment method calculation of the per-unit-length parameters of cable bundles

Abstract

A method of moments procedure to obtain the capacitance matrix for a cable bundle is presented. The geometry consists of multiple, parallel, insulated wires, possibly above a ground plane. The method uses Fourier harmonic expansion functions for the total charge and Galerkin testing functions. The capacitance matrix is obtained through the relationship of free charge to potential. Computed and measured results are presented. Where possible, these results are compared to exact analytical solutions. The effect of wire insulations on capacitance calculations is also discussed.<>
