Transmission line model with skin effect for generic circuit simulator

“…Works [6,7] presented the idea of enhancing built-in transmission model by some kind of RL ladder structure to introduce frequency-dependent line resistance (strictly speaking -impedance). Such a circuit was tested and successfully verified for evaluation (freely available) version of pspice for 10m long copper cable [8]. However using the model had to be preceded by calculations of added component values according to the line length and geometry.…”

“…Appropriate models are available in commercial (and rather expensive) circuit simulators [4,5], but unfortunately most of the popular, spice-family simulators miss the feature. Several (successful) works were already done towards implementation of enhanced transmission line model in such simulators [6,7,8]. The general structure of needed circuit supplement is known and successfully verified, however none of the publications provided method of automatic calculation of extra components.…”
