Acceleration of the Calderón preconditioned PMCHWT solver by the asynchronously parallelized NSPWMLFMA

The paper discusses about the scattering of time-harmonic waves by dielectric objects can be described by several integral equations. All of these result from the Stratton-Chu intergral representation formulas for the fields in the interior and exterior region. The most popular integral equations are the Poggio-Miller-Chew-Harrington-Wu-Tsai equation (PMCHWT) and the Miiller equation. The former results from subtracting the interior and exterior representation formulas. The PMCHWT equation is typically discretized using Rao-Wilton-Glisson (RWG) basis functions.
