Abstract: In this paper, CG -FMM is applied for the solution of RCS in electromagnetic scattering problems. Careful discussion is made on the RCS solutions for various 2 -D scatterers. Several parameters and the iterative terminate criterion have been presented. Comparing with other methods, this algorithm has more advantage when electrically large objects are concerned.
