Electric Field Integral Equation (EFIE) is widely used for solving three dimensional electromagnetic scattering and radiation from complicated structures because it is effective for both open and closed surface. But the convergence of EFIE is not as good as the magnetic field integral equation. In this paper, an efficient iterative technique for accelerating the convergence of EFIE is introduced....
The electromagnetic radiation and scattering from a body of revolution (BOR) of arbitrary shape have been widely discussed during several decades. The objects can contain perfect electric conductor (PEC), homogeneous dielectric bodies, coated conducting bodies and combined dielectric and conducting bodies. The traditional method used to solve BOR with integral equations is the Method of Moments (MoM)...
In this paper, an improved Calderon preconditioner for electric field integral equation (EFIE) with the adaptive cross approximation (ACA) algorithm is presented. The preconditioning technique based on Calderon formulas is aimed at stabilizing EFIE. A new preconditioning technique by using Buffa-Christiansen (BC) basis has been introduced in literatures recently. Because a dual refined mesh must be...
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...
In this paper multilevel fast multipole algorithm (MLFMA) based on an improved electric field integral equation (IEFIE) is developed to achieve fast solution of electromagnetic scattering from 3D open structures. The present method attains much faster convergence than traditional EFIE. And, a reasonable accuracy is also achieved in a few iterations. Numerical results demonstrate the validity and efficiency...
