@article{FierroPiccardo2021AnOP, title={An OSRC Preconditioner for the EFIE}, author={Ignacia Fierro-Piccardo and Timo Betcke}, journal={ArXiv}, year={2021}, volume={abs/2111.10761} }

The Electric Field Integral Equation (EFIE) is a well-established tool to solve electromagnetic scattering problems. However, the development of efﬁcient and easy to implement preconditioners remains an active research area. In recent years, operator preconditioning approaches have become popular for the EFIE, where the electric ﬁeld boundary integral operator is regularised by multiplication with another convenient operator. A particularly intriguing choice is the exact Magnetic-to-Electric…
