A space-mapped model of thick, tightly coupled conductors for planar electromagnetic analysis

Accurate modelling of thick metal in a planar electromagnetic analysis can require that the thickness of the metal be divided into a large number of thin sheets or layers, substantially increasing analysis time. This order of modelling is especially important when two thick conductors are separated by less than the metal thickness. This article describes a method to efficiently realize the accuracy of a large number of thin sheets by introducing a "space mapping" layer into a simple model that can be efficiently analyzed.
