Cecil, define 'sloshing.'

Hi Walt, I'm having trouble with my news-server so I am posting from
Google using procedures to which I am not accustomed.

The classic wave reflection model indicates that forward power travels
from the source to the load where it is incident upon the load. At a
load mismatch, some of the forward power is rejected and travels back
from the load toward the source as a reflected wave. For instance, in
the following lossless example, we have 104.17 watts of forward wave
and 4.17 watts of reflected wave on the 75 ohm line. This is all in
line with "Reflections" and my unpublished article.

100W--50 ohm line--+--1/4WL 75 ohm line---112.5 ohm load

As I infer/understand what Roy, and others, have said while objecting
to the material in my unpublished article:

The only real forward power wave is the one that is dissipated in the
load. The reflected power wave doesn't travel from the load back toward
the source and the extra 4.17 watts in the forward wave doesn't travel
from the match point back toward the load. The energy associated with
the reflected waves just "sloshes" around in the transmission line and
doesn't move very far or very fast and certainly not in the form of EM
wave components.

So Roy's use of the word "slosh" in the context in which he used it, is
all I can give you. Roy hasn't defined the word and neither has the
IEEE. :-)
