Accurate and highly convergent solution of integral equations for electromagnetic problems

Surface integral equations (SIEs) are commonly used in the solution of electromagnetic scattering and radiation problems. Among various SIEs, the magnetic-field integral equation (MFIE) and the Muller formulation, when solved using a traditional moment method, are known to have worse accuracy but faster iterative convergence compared to the electric-field integral equation and the Poggio-Miller-Chang-Harrington-WuTsai equations. In this paper, newly proposed techniques are adopted in the discretization of the MFIE and the Muller formulation, leading to numerical solutions with both excellent accuracy and fast convergence.
