A recently introduced potential integral equations for stable analysis of low-frequency problems involving dense discretizations with respect to wavelength are solved by using the fast multipole method (FMM). Two different implementations of FMM based on multipoles and an approximate diagonalization employing scaled plane waves are developed and used for rigorous solutions of low-frequency problems. Numerical results on canonical problems demonstrate excellent stability and solution capabilities of both imp...

The forward model analysis in a multiple input multiple output (MIMO) system requires the computation of the signals received by receiver antennas when various targets are illuminated by a transmitter antenna. The full wave analysis of such systems provides accurate results with high computational cost. Fast analysis of the system can be achieved by simple models based on several approximations which limits the accuracy. In this thesis, a modeling technique that provides better accuracy compared to simple m...
