The random auxiliary sources method: A simple, fast, and efficient electromagnetic scattering computations approach

Abstract

A simple, fast, and efficient approach to solve the electromagnetic (EM) scattering problem from arbitrary object is offered by the Random Auxiliary Sources (RAS) method. Based on direct application of the boundary conditions and projection of radiating modes with infinitesimal sources, the method is able to accurately solve problems with much less execution time than other comparable methods. The method is verified and compared to the Method of Moments (MoM) for 2D and 3D problems for accuracy and speed.
