An approach of fast multipole method to scattering of clustered, electrically large and conducting cylinders

A numerical simulation of electromagnetic scattering (EM) from clustered, electrically large and conducting multi-bodies is implemented by using the exact Fast Multipole Method (FMM). The FMM speed is much faster and more effective than the moment method. Bistatic scattering from four clustered, electrically large and conducting cylinders, and the current distribution on the surfaces are calculated by the FMM. The functional dependence of bistatic scattering upon the distance between the cylinders and other parameters is numerically discussed.
