Modeling of power distribution networks with retardation using the transmission matrix method

This work describes the analysis of multilayered power distribution networks that include signal lines and vias. The signal lines are modeled as transmission lines, and vias are represented as not only self and mutual inductances but also include retardation currents. The structures have been analyzed using the transmission matrix method (TMM) in the frequency domain. Analysis using the TMM provides considerable savings in memory compared to SPICE.
