Abstract

A modified electric field integral equation (MEFIE) is proposed to realize fast and accurate solution of 3D electromagnetic scattering. By adding the principle value term of magnetic field integral equation (MFIE) operator into original electric field integral equation (EFIE) operator, a well-conditioned modified EFIE operator is constructed. To avoid the loss of accuracy, a appropriate iterative technique with stable convergence is developed. The present method reduces greatly the condition number of EFIE, attains much faster convergence than EFIE. And, a reasonable accuracy is also achieved by few iterations. Numerical results demonstrate the validity and efficiency of the MEFIE.
