Abstract

This paper presents a novel symmetric FEM-BEM formulation for solving unbounded electromagnetic problems. The beauties of the proposed method include: (1) symmetry, (2) modularity, (3) non-conformity between FEM and BEM domains, (4) free of internal resonance, and (5) natural and very effective preconditioning schemes that guarantee spectral radius less or equal to one
