Abstract :
This work presents the combination of the Unscented Transform (UT) with the Method of Moments (MoM). This combination allows the modeling of uncertainty in electromagnetic computations. The procedure shows results with accuracy similar to the Monte Carlo approach, but using a much smaller number of simulations. This work uses standard MoM based solvers. The validation of the technique used frequency domain tests. The results show good agreement compared to Monte Carlo outcomes with much reduced simulator use.
