An efficient simulation technique for lossy substrate interconnects characterization

In this paper, an efficient numerical simulation technique is introduced to extract the propagation characteristics of interconnects over lossy substrate structures. This approach is based on a compact-form FDFD method in conjunction with the two-step Lanczos (TSL) technique. The efficiency and accuracy of the algorithm are demonstrated through the simulation of several lossy transmission-line structures. © 2004 Wiley Periodicals, Inc.
