Abstract :
This paper presents a new closed-form passive time-domain macromodeling algorithm for distributed lossy multiconductor transmission lines (MTLs). The method is based on a sixth order finite element method (FEM) approximation and offers an efficient means to discretize MTLs compared to conventional lumped discretization (Paul, 1994) while preserving the passivity of the macromodel. It is shown that due to the high efficiency of sixth order approximation, the proposed macromodel requires only a few elements to achieve good accuracy. In addition, the FEM macromodel can include frequency-dependent per-unit-length (p.u.l.) parameters and can be extended to nonuniform transmission-lines (NUTLs).
