Abstract :
A new ℋ2-matrix based kernel-independent algorithm of linear complexity is developed for the surface integral equation based impedance extraction of arbitrarily shaped 3-D lossy conductors embedded in dielectric materials. The new algorithm greatly accelerates the iterative solution of a scalar-based surface integral equation for impedance extraction. It outperforms state-of-the-art iterative impedance solvers with fast CPU time, modest memory consumption, and without sacrificing accuracy, for both small and large number of unknowns.
