My network theory is self-taught, so maybe there are some basic answers to this, but while writing my thesis this keeps coming up:
Why aren't power waves (as defined by Kurokawa's scattering matrix paper) see more use than travelling waves in research and literature? Seems to me that the power wave reflection coefficient s has more utility than the travelling wave reflection coefficient Γ, especially at circuit junctions where the impedance looking in both directions is complex. Perhaps it is because it is much more difficult to measure power waves than travelling waves with a VNA? Is there even a method to experimentally measure s at a junction with arbitrary impedances?
