Uncertainty Analysis in EMC Simulation Based on Improved Method of Moments

Abstract

Recently, many uncertainty analysis methods have been taken into consideration in electromagnetic compatibility (EMC) simulation. As a traditional method, the Method of Moments (MoM) owns many advantages compared with other methods, especially in calculating the high dimension problems. However, its main disadvantage is the poor accuracy. In this paper, the Richardson extrapolation has been used to improve the MoM in order to promote the accuracy. By using feature selective validation (FSV), the effectiveness of the improvement can be obviously shown compared with the standard results calculated by the Monte Carlo Method (MC).
