Abstract

In this paper, we present an incremental multilevel matrix filling and sparsification scheme for the method of moment (MoM) solution of the electric field integral equation at low and very low frequencies. The proposed scheme allows a strong reduction of the memory requirements without a loss in accuracy. Numerical results show the method performance in terms of memory requirements, CPU time and accuracy with respect to the standard MoM, the multilevel fast multipole algorithm, and the adaptive cross approximation.
