Default Phase array question

May we assume that the term "4th mechanism of reflection" will be

Yes, exactly as it has been for the past six months since
I revised my article. In less time than it takes to condemn
me for saying something in the far distant past, you could
have just read my article. Here's the half-year old footnote
from my article.

[10] Revision 1.1, Feb. 20, 2008 - In the original version, the
redistribution of energy due to wave cancellation was dubbed a
"reflection". W5DXP has dropped that designation in favor of a
"redistribution" as described by the FSU web page. The word "reflection"
is reserved for describing something that happens to a single wave when
it encounters an impedance discontinuity. The word "redistribution" of
energy is adopted for describing what happens to the energy in canceled
waves. In like manner, since interference can occur with or without wave
cancellation, any reference to interference as the cause of the
redistribution of energy has been removed.

You convinced me that power doesn't flow.


Thank you, Jesus.


That was at least eight years ago, Jim. What is wrong with
you? I have no doubt that six months from now, you will again
be accusing me of believing that power flows. You seem to be
suffering from dementia.

Which of course explains how it is that your answers come out correctly.
I believe I already mentioned that it does (obviously) produce correct
answers, given all the underlying assumptions are correct.


However, correct answers don't seem to be enough for you.
You seem to be looking for a stone tablet handed down from God.

If you want, you can convert the Bird wattmeter reading to
irradiance by dividing by the cross-sectional area of the
coax.


Wouldn't I first have to buy into the idea that power is flowing through
it? :-)


No, irradiance, like power, doesn't flow. If you don't know
that, that's probably the source of your confusion.

It's hard to imagine how a simple, mutually agreed upon statement of
fact could be construed as a "false strawman implication", but there it is.


Your multiple unethical attempts to imply that I said power
has a phase angle is more than obvious to everyone.
