Combined PEEC/MoM solution technique for efficient electromagnetic emission calculations of PCBs in metallic enclosures

The paper presents modern simulation techniques using the method of moments (MoM) and the partial element equivalent circuit (PEEC) method to deal with electromagnetic emission of printed circuit boards (PCB) with respect to surrounding enclosures. The inclusion of all types of SPICE circuit elements is possible. Reflection and diffraction effects of the emitted field from PCBs at the enclosures can be considered. The combined solution technique with PEEC and MoM easily fits into the industrial workflow while guaranteeing accurate results compared to closed-solution techniques. The approach is illustrated by means of some examples and comparisons with closed-solution techniques and measurements are given.
