The Method of Auxiliary Sources in Applied Electrodynamics Problems

This article presents an overview of our works in applied electrodynamics using the Method of Auxiliary Sources (MAS). The details of the correct selection of auxiliary parameters for efficient use of the MAS are presented. The importance to consider Scattered Field Singularities (SFS) is discussed. Considering SFS and some recommendations based on many years of experience, the MAS is expanded for large body and large scenarios scattering, eigenfields, and eigenvalues problems as well as inverse problems solution, sharply minimizing at the same time the required computational resources.
