Abstract :
The potential of the interpolative decomposition multilevel fast multipole algorithm (ID-MLFMA) on developing an effective preconditioning technique for multiscale, dynamic electromagnetic problems are analyzed. The preconditioner based on multilevel inverse-based ILU is developed for ID-MLFMA. The proposed preconditioning technique is investigated by numerical experiments on complex targets.
