Unfortunately, I don't have the modeling software that Wes
is using. And I have already demonstrated the effect using
inductive loading stubs modeled with EZNEC.
Reg has already said that real-world coils with Ls, Cs, & Rs,
can be treated as transmission lines. Rhea's paper on a new
solenoid model agrees with Reg. Have you ever seen a transmission
line less than 1/2WL long where the current-in is equal to the
current-out when there are standing waves present? Even in a
transmission line without reflections, the current-in is never
equal to the current-out in magnitude and phase except for
lossless lines at the N*wavelength points.
Most of this stuff is common sense for anyone who thinks that
reality should dictate the model, not vice versa. Einstein once
said that all our models are flawed.

I know Reg has said that. He's not the first nor will he be the last.
That's not the only way to look at it, however, and I doubt if it's the
best under all circumstances. In order to show that an inductor can
be treated as a transmission line, in the way you want to do it, you
have to show that your inductor has an exponential current gradient
along its length when it's terminated in a certain impedance. I don't
think you've thought much about how that can be done. Yuri
says he's going to try to show something of the sort using fish tank
thermometers. At least he's making the attempt.
