Abstract

To further expedite solution of electromagnetic scattering from conducting structures with slots, a novel improved electric field integral equation (IEFIE) is developed to reduce the iteration time in multilevel fast multipole algorithm (MLFMA). By adding the principal value term of magnetic field integral equation (MFIE) operator on the both sides of the EFIE operator, a well-conditioned improved EFIE operator is constructed. To achieve a reasonable accuracy, only several update steps for the unknown current is required. Numerical results demonstrate the validity of the present method.
