Broadband electromagnetic analysis of interconnects by means of TLM and Krylov model order reduction

The transmission line matrix (TLM) method is combined with Krylov subspace-based model order reduction (MOR) processes for the extraction of the broadband electromagnetic response of planar interconnect structures. A scattering-symmetric Lanczos algorithm is used for the computationally efficient generation of a broadband, reduced-order model for the multiport transfer function matrix of an interconnect structure. The passivity of the generated reduced-order model and its accuracy down to DC are demonstrated through the modeling of a typical, planar interconnect structure.
