| Abstract: | Iterative method of integral equation is used to de electromagnetic scattering from multiple conducting cylinders in this paper. The fast multipole method (FMM) is used to calculate the interaction between each subscatterer in the iteration process, and it expedites the calculation of matrix-vector multiplication. Meanwhile the biconjugate gradient (BiCG) method instead of the conjugate gradient (CG) method is ed to accelerate the iteration process. The high efficiency of the present method is shown by the numerical results. |
