Systematic derivation of reference circuits for wave digital modeling of passive linear partial differential equations
Christiane Leuer, Karlheinz Ochs · 2009
Finding an appropriate reference circuit, is an integral part of numerical integration using wave digital (WD) concepts. We show an approach for the systematic derivation of a canonical internally passive electrical circuit from a class of linear partial differential equations (PDEs). We present two methods to transform this circuit into a reference circuit, having a one-to-one corresponding wave digital structure. As an example, we deduce a reference circuit for a wave digital algorithm from Maxwell's equations and depict simulation results.
