Dealing with complexity in EMC modelling

The paper addresses features of EMC which make it a particularly challenging modeling applications. These features include the very broadband nature of the interactions taking place thus encompassing regions of non-linearity and of uncertain parameter values; the inherent uncertainties in the geometrical configurations and dimensions of the multitude of components; and the ubiquitous presence of multi-scale features. The challenge thus is to address complexity without resorting to extremely lengthy computations which require enormous computational resources and tedious and time consuming problem definition and input data preparation. The emphasis of this paper is on the embedding of macromodels to describe complex materials and the treatment of uncertainties.
