Incomplete LU Factorization Preconditioner for the Efficient Solution of Improved Electric Field Integral Equations

摘要：

This paper is a study on the numerical solution of linear systems arising from the discretization of the improved electric field integral equation (IEFIE) for electromagnetic scattering problems. Using incomplete LU factorization preconditioner, the IEFIE is solved by generalized minimal residual iterative method in the context of the multilevel fast multipole algorithm (MLFMA). Numerical results show that the efficiency and robustness of the solution can be significantly improved by contrast with the conventional EFIE formulation.
