Characteristic Mode Equations for Non-Symmetric Surface Integral Operators

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review

Abstract

The magnetic field integral operator (MFIO) based characteristic mode formulation for closed perfect electric conductor is considered. Since the MFIO is non-symmetric, we need to consider the eigensolutions of both the MFIO and its transpose operator for a characteristic mode expansion. The eigenvectors of the transpose of the MFIO are shown to be in the dual of the range of the MFIO. Physically, these vectors can be interpreted as the tangential electric field on the surface.
