Computational modeling of uncertainty in time-domain electromagnetics
We discuss computationally efficient ways of accounting for the impact of uncertainty, e.g., lack of detailed knowledge about sources, materials, shapes etc, in computational time-domain electromagnetics. In contrast to classic statistical Monte Carlo based methods, we explore a probabilistic approach based on high-order accurate expansions of general stochastic processes. We show this to be highly efficient and accurate on both one- and two-dimensional examples, enabling the computation of global sensitivites of measures of interest, e.g., radar-cross-sections (RCS) in scattering applications, for a variety of types of uncertainties.
