COMPUTATION OF CAPACITANCE COEFFICIENTS OF RECTANGULAR THICK PATCHES ON MULTILAYERED SUBSTRATES

This article presents an alternative method to compute the capacitance coefficients of a system of rectangular thick patches on a multilayer ed substrate. Following the M-strips, previously developed to analyze infinite length transmission lines, the conductors are modeled by a se t of zero-thickness plates at the same potential. The capacitance coef ficients of the model structure are obtained after applying the Galerk in's method in the spatial domain. A suitable approach for computing t he static spatial Green's function is also presented. (C) 1996 John Wi ley & Sons, Inc.
