Abstract :
This paper presents a computationally efficient approach to performing electromagnetic simulations in the presence of statistically defined uncertainties caused by either material in- homogeneities, or fabrication and placement tolerances. Comparisons are made with results from Monte Carlo simulations and a sequence of higher order approximation extensions to the technique. It is shown that accurate results are possible within practical computational limits for the case of small parameter variations.
