Hey Tom, have you noticed the only time I get ploinked is
when some guru is on the verge of losing an argument? Is
saving face worth sacrificing integrity?

The only important thing is you supply representative inputs to a device
and it gives you the correct product of the numbers as its outpot.


Apparently, Ian is too young to remember analog multiplication
by non-linearly calibrating the face of linear meters which is
exactly what Bird does.

And if that source WERE entirely coherent?


If that source were entirely coherent, superposition
between the forward waves and reflected waves would
result, obeying the laws of physics. Some areas could
be very bright obeying the total constructive interference
equation. Some areas could be totally black obeying the
total destructive interference equation. You really
should read _Optics_, by Hecht and get back to us.

The above is EXACTLY how antenna radiation patterns
are achieved.

So what is E^ x H^?


According to Born and Wolf, it's "an abstraction that introduces a
certain degree of arbitrariness". On the other hand it's integral over
a volume is described as something from which "no unambiguous conclusion
can be drawn". So, is that what you're hangin' your hat on, there Cecil?


Actually, the Poynting Vector is extremely well defined *AND* well
accepted in the RF engineering community. Do you really reject the
Poynting Vector concept? If so, that explains everything.

You're still presenting that straw man riding that dead horse.
Please read my lips, Jim. *ENERGY CANNOT BE CANCELED*!!! Waves
can be canceled but the energy in the canceled waves must
change direction in a transmission line because there are
only two directions available. When fields cancel in one
direction, the energy in the fields must be re-distributed
in another direction. Given two, and only two, directions for
that re-distribution in a transmission line, what is it about
the following that you refuse to understand?

"... when two waves of equal amplitude and wavelength that are
180-degrees ... out of phase with each other meet, they are not
actually annihilated. All of the photon energy present in these
waves must somehow be recovered or redistributed in a new direction,
according to the law of energy conservation ... Instead, upon meeting,
the photons are redistributed to regions that permit constructive
interference, so the effect should be considered as a redistribution
of light waves and photon energy rather than the spontaneous
construction or destruction of light."

Also, this discussion bears upon the answer to
"What is the wavelength of Glare?"
that has remained undiscovered by binary engineers. I bet our Readers
can catch this clue. :-)


Richard, you apparently are not reading my postings. The
wavelength of glare is exactly the same as the wavelength
of the single-frequency coherent laser forward wave
emissions. Do you want me to re-post the equation for
wavelength Vs frequency?

It probably wouldn`t work, but you might say to the policeman: I didn`t

There was a guy in my home town, who for decades, honked his
horn when encountering a red light, because he was color blind.
Everyone knew he would just blow through a red-light, honking
his horn, so everyone gave him the right-of-way. Finally, he
encountered a deaf person ...

EXACTLY!!! When the glare is exactly the same frequency as the
forward laser beam, and when refraction has been eliminated,
as it is in a transmission line, your postings become completely
irrelevant, but I am not surprised since you seem to be protecting
some cow you consider to be sacred.

Then my reminder of that fact (above) must have served its purpose. I
wrote it in response to your claim that power cancels at a Z0-match
point. Hellooooo... anybody home?

If I ever said, "Power cancels at a Z0-match", I made a mistake.
I don't think I ever said that and I believe that to be only one
of your numerous straw men, but if you will provide a valid reference,
I will take it back and appologize for my mental mistake. I am not
perfect, BUT the onus of proof is upon you. You can provide a reference
for your assertions, can't you, Jim? :-) (In case you missed it, this
is a challenge to your integrity.)
