Abstract :
A weak-form GMRESIR-FFT method is developed for iterative solution of 3D volume electric field integral equation. Approximate eigenvectors are employed by using implicit restarting scheme to alleviate the ill effect of restarting in GMRES iteration process, and hence improves convergence. Numerical experiments are conducted, which show that GMRESIR-FFT is more efficient and robust than the conventional CG-FFT and BCG-FFT methods
