The capacitive coupling between two microstrip lines crossing diagonally above a ground plane in a multilayered dielectric substrate is analyzed through a quasistatic approach based on the space-domain integral equation method, The typical evolutions of the normalized lumped excessive capacitances for nonorthogonal crossover configurations are presented.

A clever way to simulate Numerically Matched Loads is presented and applied in the mathematical framework of 3-D spectral domain analysis. The numerically matched loads already have been developed in the particular case of the spectral domain approach using a set of subsectional rooftop expansion and testing functions in the moment method. In order to properly model more complicated structures, we propose in this letter an extension of the NML simulation where triangular subdomain functions are used as both expansion and testing functions in the moment method. © 1997 John Wiley & Sons, Inc.
