Algebraic preconditioners in method of moments (MoM) are often constructed from the filtered near-field interaction (NFI) matrix. However, the criterion for filtering NFI matrix is an art rather than science, and the resulting preconditioner suffers seriously from the lack of global interaction information. The proposed methodology is aimed to relax these limitations by the skeletonization. Numerical experiments have been performed to show efficiency and effectiveness of the proposed methodology.
