In this paper, a preconditioning technique based on the null field method is presented to accelerate the convergence of fast near-linear complexity iterative Method of Moments (MoM) solution. For large-scale package-board 3D fullwave parasitic extraction, the solution time is often prohibitive for use in a design-cycle which might necessitate several analysis stages. The bottleneck is often the slow-convergence of the Krylov subspace-based iterative solution. Since the null field method scales the near field interactions to a block-diagonal form it can be used as an efficient preconditioner as shown in the numerical experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
