Abstract: The multilevel complex source point (MLCSP) method is used to solve augmented electric field integral equation (AEFIE) for perfect electric conduct target. As an effective solution of the low-frequency problem, AEFIE separates current and charge to avoid the imbalance between the vector potential and the scalar potential in the conventional electric field integral equation (EFIE). In order to reduce the computational complexity of method of moment (MoM) for AEFIE, the vector potential and scalar potential are expanded by complex source point (CSP). Then, an aggregation operator is introduced to form a multilevel algorithm for acceleration the matrix-vector products. The numerical results showed that, the accuracy of the method is very high when solving low frequency electromagnetic scattering problems and circuit problems, while computational complexity can be reduced to O(N)level.
