One of the tests the traveling wave analysis must pass is that the

reverse current wave excitation must equal the results from excitation

superposition, whether the network is lumped or distributed.

It certainly does that within the bounds of the principle of
superposition. But as I earlier pointed out, like two superposed
PSK modem signals, phase information is lost in the superposition.
You used standing wave current phase to try to measure the phase
shift through a coil. Your attempt was futile since the standing
wave current phase doesn't contain any phase information.

And analysis based on a distributed model, as Ian says, must converge to
the same results as a model with lumped components as the physical sizes
of the components get very small.


And it certainly does. But the distributed network model works
for antennas and transmission lines where the lumped circuit model
fails. The lumped circuit model is supposed to fail for transmission
lines and antennas.

Analyses of the examples using lumped models with total current have
been entirely adequate to explain the observed inductor currents.

Maybe for you, Roy, but not for me and others. Are the four elements
of earth, air, water, and fire adequate to explain the physical
world to your satisfaction?
