Default Standing-Wave Current vs Traveling-Wave Current

Any model that violates the laws of physics is fundamentally
flawed. Your model has EM energy sloshing around like water.
Your model has EM energy neither flowing into the source
nor being reflected. That is a violation of the conservation
of energy principle.

The SPICE simulation of the circuit I analyzed was, of course, a
transient analysis. The source was a perfect voltage source which
produced a sine wave beginning at t = 0 and continuously after that,
just as in my analysis. For anyone having SPICE, here's the netlist:


What is it that you think you have proved? That there
is no energy in reflected waves? That EM waves don't
move at the speed of light? That the conservation of
energy principle is invalid? What?
