By modifying the construction of the combined-field integral equation (CFIE), we demonstrate a significant improvement in the iterative solution of these problems compared to the conventional electric-field formulation.EnglishIntegral equationsIterative methodsMultilevel fast multipole algorithmExtending the applicability of the combined-field integral equation to geometries containing open surfacesArticle10.1109/LAWP.2006.8875521548-5757
