Abstract

Accurate simulations of printed circuit boards (PCBs) with power bus are of concern to EMC engineers. Recently the new circuit extraction tool CEMPIE-PEEC has proved to be a robust method for full-wave numerical modeling of printed structures. Nevertheless some sharp odd resonances have been observed in the simulation of some structures. This paper tries to give insights into the reasons of these singularities through comparisons of the CEMPIE-PEEC results with integral - MoM - and differential - FDTD - full-wave methods.
