Abstract

Abstract: Numerical simulation of electromagnetic scattering from electrically large multiconducting bodies has been implemented by using the exact fast multipole method (FMM). Scattering cross sections of four clustered, conducting cylinders and the distribution of electricity on the surfaces are calculated by the FMM. The calculation speed of FMM is much superior to the conventional MOM's. The functional dependence of RCS and surface current distribution upon the distance between the cylinders, and other parameters are numerically discussed.

Key words: electromagnetic scattering, MOM, fast multipole method, multi objects
