Over the past 20 years numerical methods have become an indispensable part of the design and analysis process for antennas, optical and microwave devices, and many other electromagnetic structures. However, as computational electromagnetics become more refined, the old computer adage “garbage in, garbage out” looms as an increasingly large problem.

In particular, the input parameters for many practical electromagnetic simulations cannot be exactly quantified, and must be treated as uncertain. These uncertainties will induce randomness in the desired outputs (e.g., radiation patterns and device or circuit responses). Due to the complicated field interactions inherent in electromagnetics, this randomness can be very difficult to quantify. At present, such uncertainty in electromagnetic problems is largely ignored, due to the huge computational cost involved in running multiple Monte Carlo simulations.

This talk will outline the problems of ignoring uncertainty, and highlight recent research into methods that reduce the computational costs of incorporating uncertainty in numerical methods for electromagnetics.

This talk is part of the Electromagnetic Communications and Sensing Research Seminar Series series.
