Abstract
Using the Method of Moments, the computation of the near-field interactions requires to evaluate 4D singular integrals. Recently, a method has been proposed to compute these integrals fully analytically, rapidly providing accurate results. In this paper, we reformulate the analytical technique to highlight the different intermediate results that are involved in the full procedure. We show that, by storing and reusing intermediate results, the evaluation of the singular integrals is accelerated by several orders of magnitudes.
