Numerical Validation of Smallest Singular Value Estimation Techniques Applied to Localization of EFIE Interior Resonances.

Abstract

The localization of the interior resonances of EFIE is an important task in order to protect the moment method computation from numerical deterioration caused by their presence. In this paper, a method to locate these cavity resonances is proposed and discussed. Numerical results for the electromagnetic scattering by some PEC metallic objects, are presented
