This paper presents a computationally efficient approach to performing electromagnetic simulations in the presence of statistically defined uncertainties caused by either material inhomogeneities, 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.
