Abstract

The fast multipole method (FMM) dramatically reduces the time and memory required to compute radar cross sections and antenna radiation patterns compared to dense matrix techniques. We have implemented the FMM in a method of moments (MoM) program to compute electromagnetic scattering from large bodies of arbitrary shape. We compare the memory and time required using the FMM to that for direct and iterative solutions using a dense impedance matrix.<>
