Abstract

The low-frequency stability of inverse surface source field transformations based on the electric field integral operator (EFIO) together with the boundary element method (BEM) is investigated. In order to overcome the observed breakdown, we study a stabilization scheme based on quasi-Helmholtz projectors. This scheme incorporates a self-adaptive normalization and a stabilized right-hand side (RHS) evaluation which are found of critical importance to determine all fields accurately as shown by the simulation of different inverse surface source reconstructions.
