Abstract :
A novel accelerated algorithm is proposed, which suggests a solution for arbitrarily shaped, three-dimensional (3D) perfecly conducting scattering objects. The method is an innovative combination of a stationary iterative solver, the Forward-Backward Method (FBM), and a renowned accelerated scheme, the Multilevel Fast Multipole Algorithm (MLFMA). The accuracy and computational efficiency is then carefully investigated in a comparison with conventional methods to demonstrate the advantages of the proposed technique.
