The use of Unscented Transforms for statistical analysis in EMC

Abstract

The use of unscented transforms UT for the statistical analysis of nonlinear linear problems is described. The UT methodology is then applied to the analysis of wire coupling within an enclosure which is a typical problem encountered in EMC studies. The UT results are compared with the more traditional Monte Carlo approach. It is demonstrated that UT is a powerful technique that can greatly improve the computation of the uncertainty encountered in many EMC studies.
