Is antenna a transducer to 377 ohms?
Richard:

Beliefs. -sigh- Is this one of those transcendental statements about
navel gazing?
[snip]
No... it's not transcendental it's purely algebraic! (grin)
[snip]
Everywhere...
Even in the near field of an antenna.
No. Not even in the near field of an antenna.
[snip]
Where then is Zo = 377 Ohms?
[snip]
That is an antenna itself has no effect on the fundamental u and e of the
media in which it is immersed.
Wrong.
[snip]
Surely uo, eo, Zo and c (velocity of light) are fundamental and invariant
properties of "free space", no?
[snip]
After all the antenna is very small, and free space is very large (grin),
and so a tiny antenna cannot change u and e everywhere!
Abstracting from near space to everywhere is the source of your error.
[snip]
No, I'm "contracting" from outer space to near space... using the
contravarient tensor!
[snip]
The waves are not plane where the waves are not plane, but... Is this
a Zen "but?"
[snip]
If a tree falls in the forest and no one is there to hear it, does it make a
sound?
If an antenna radiates somewhere in the Universe and there are no receivers,
does it really radiate?
[snip]
There might just also be plane waves passing through identically the same
region of space, say emanating from a more distant antenna.
Wrong.
[snip]
Oh, and here I thought that at least tiny remnants of all radiation
eventually passes through every part of space, filling all of space as it
expands throughout the Universe..
[snip]
The ratio for
those plane E and H fields will indeed be 377 Ohms over the exact same
region of space where Zo is different because of simultaneous but
non-planar
waves.
Wrong.
[snip]
I know that Special Relativity [Maxwell's equations] is not supported in
full by General Relativity, but surely even though space is warped by mass,
superposition must still be supported. The radiation in your neighbourhood
is a superposition of suitably delayed and reduced (by path attenuation) of
all radiation, no?
[snip]
So in fact... the wave impedance of free space can have many values
simultaneously, one [universal?] constant value of ~377 Ohms for plane
waves, while it may have many other [arbitrary] values for waves passing
through the same region of space that are not plane.
Thoughts, comments?
Wrong.
[snip]
And here I thought I was going to be able to sell you a little corner of the
Universe [very near the Brooklyn Bridge] that has any Zo you want. What?
[snip]
Peter, are you trying to bust loose a seized bearing? Most of this
reads like the Molly Bloom citation from a technical translation of
"Ulysses."

Molly Bloom? How did she get into this... I thought she was still living in
the house on Eccles Street". What?
Now Ulysses, he's my man!
I miss Reg Edwards already :-(
