Digital Wave formulation of quasi-static Partial Element Equivalent Circuit method

This paper presents a digital wave formulation (DWF) of the quasi-static Partial Element Equivalent Circuit formulation. Through the use of a pertinent change of variables and the choice of a specific implementation of PEEC cell elements in the Digital Wave domain, the standard PEEC model is transformed into and solved as a wave digital network. The example reported shows the accuracy and the significant speed-up of the proposed DWF-based PEEC solver when compared to the standard Spice solution.
