Oh poo. At current nodes charge piles up and spreads out, on
alternating half cycles. For one half cycle, the pile is positive, and
for the next it is negative. This is a basic transmission line
concept. If transmission lines had no shunt capacitance, there would be
no place to put this charge. But there is, so it is no problem. Whether
the transmission line is coax, twin line or a slow wave helix makes
little difference. The process is similar. Isn't this what you have
been arguing?

If the forward traveling wave is equal in magnitude at both ends of the
coil, there is no net storage of energy due to the forward traveling wave.

If the reflected traveling wave is equal in magnitude at both ends of the
coil, there is no net storage of energy due to the reflected traveling
wave.

Superposing those two waves still results in no net storage of energy.
Sorry, got to hit the road.
