What you describe as reflection and re-reflection occurs between the
mismatched antenna and the tuner that has been adjusted to minimize
power returned to the transmitter. The sole function of the tuner is
to keep this power from being dissipated by the transmitter (common
experience of arcing, denoting a voltage reflection, or thermal
runaway, denoting a current reflection). The "virtual" reflection
(offered by the tuner) is generally know as the complex conjugate of
the remote load, seen at the near end of the line through which it is
returning. This means that the line transforms the phase and
amplitude of the reflection, and the tuner's job is to invert that
relationship to counteract it, and return it to the antenna.

There are both wave descriptions of this process, and lumped circuit
equivalents. Both work, and both describe the same process from
different points of view. One does not negate the other's validity
(unless, of course, you attempt to mix the points of view and demand
consistency in terms - a frequent rhetorical trap here).

There will no doubt be a flurry of denials to this simple example with
contortions of logic to match. As for the math, you will find it by
the reams, once you've been overwhelmed with the arcana of hyperbolic
descriptions of a novel physics that have to proceed its proof.

Keep your eye on how your literal points in your question go abandoned
with these arcane theories.

====================================

Dear Richard, you are confusing the matter even further, if that were
possible.

The only saving grace about your tedius message is that you yourself
eventually realise what a load of overcomplicated nonsense it is.

Reflected power is a mere fiction. Power which is not radiated from an
antenna never actually arrives there. In fact it never leaves the
transmitter.

All the power which leaves the transmiter is radiated except for that which
is lost in the line. It has nowhere else to go!

But for the existence of so-called SWR meters, the words 'forward and
reflected power' would never enter people's vocabularies. For the few who
become involved with such matters, the misleading fiction also appears in
the language of mathematics.

Names have to be invented in order to discuss mathematical equations in
plain English. But there's no reason why they should be propagated, just to
confuse, into the real World.

The sole purpose of an SWR meter is to indicate whether or not the
transmitter is loaded with 50 ohms.
