This reminds me about a discution about hole propagation in semiconductors
:)
This chap could not imagine that a "hole" could propagate thru solid mater
:)
In principle you are right. And this is the "consecrated" definition that
all of us are programmed into their colleges. However one can look to SWR
from a different perspective.
I say that SWR is an INTERFERENCE pattern created by vector addition between
the incident wave and reflected wave. As BOTH waves are moving the
interference pattern moves to. Thus when you say you have an E node ( a
voltage Minima/Maxima) then you actually saying that the PATTERN is at
minima/maxima. This is MY concept of SWR. As I said before, it really does
not exist but is a MODIFIED incident wave, modification that can be seen as
modulation.
I have experimented with Variable Reactance at the antenna end just to find
out
the modulation efficiency of such a idea ... Work is still in progress.

If we can accept the notion that GUNS are
the killers and not the people, why is it that
we can not accept the idea that CARS are
the speeders and not the drivers?
Alex, trying to understand the world around.
