A point‐wise approach that can be used efficiently in the numerical solution of Electric Field Integral Equations is introduced. The algorithm is based on the so‐called magic distance concept, which defines exactly the point‐to‐point equivalent of a four‐dimensional integral. Magic distance values are rigorously obtained in the electrostatic case and their usefulness is demonstrated. The concept is generalized to the electrodynamic case, resulting in a family of very simple “magic‐distance inspired” algorithms that maintain the overall accuracy of Galerkin formulations without appreciable deterioration in the overall accuracy. © 2013 Wiley Periodicals, Inc.
