The distribution of radiation centers plays an important role in the auxiliary sources method. It has a decisive influence on the accuracy of solutions, the convergence rate and the computation cost. The optimal selection of the MAS (method of auxiliary sources) parameters (auxiliary surface, position of radiation centers) is considered an open issue. This work presents a systematic optimization framework to achieve the optimal configuration of the MAS for scattering by an infinite arbitrary-shaped cylinder.
