Abstract
In this paper, the IE-FFT has been successfully implemented with the curvilinear basis function to solve scattering problems. The IE-FFT is used to speed up the matrix-vector multiplication. The CPU time per iteration is O(N1.5log(N)) and the memory requirement is O(N1.2). The MN preconditioner has been used to improve the convergence of the CG solver and the good performance has been shown. The speed up can achieve 6 times. The numerical results show that the IE-FFT has good accuracy and efficiency.
