Creating EMI/EMC Models
The art of creating practical EMI/EMC models is to ensure that only sufficient detail is included to represent the physical problem accurately. Too many details can lead to overly complex models that require excessive computer resources. Too few details and the results obtained may not provide a true picture of the problem’s behavior. Fortunately the middle road between the two extremes is fairly wide, and the balancing act is one that is mostly learned from experience in modeling specific types of problems. A set of generic model construction plans are given to provide a starting point for the creation of any EMI/EMC model. These plans are then used to develop specific examples, which have been chosen to highlight the strengths of the various techniques.
