Where then is Zo = 377 Ohms?

Hi Peter,

To how many places? Your question is rather oblique when we are
discussing near fields and antenna as "transducer" [not a choice of
term I subscribe to].

I seriously doubt that you've unhinged from the origins of that value,
however, it bears only tangentially on the matter.

That is an antenna itself has no effect on the fundamental u and e of the
media in which it is immersed.

Wrong.

Surely uo, eo, Zo and c (velocity of light) are fundamental and invariant
properties of "free space", no?

And some toothpaste makes our teeth whiter, no? Your reply does
nothing to answer your error, however.

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.

No, I'm "contracting" from outer space to near space... using the
contravarient tensor!

Then you have misapplied it, clearly. Arguing does not take the place
of easily demonstrable facts. AH! forgive me, wrong forum, arguing
is classic substitution. However, the entertainment value is rather
poorer this round.

There might just also be plane waves passing through identically the same
region of space, say emanating from a more distant antenna.

Wrong.

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..

Are "thoughts" related to "beliefs?" Bloated speculations of
background radiation don't change the basic assertion that in the near
field, there is nothing that remotely approaches the presumed 377 Ohm
specification. You've both (earlier) acknowledged this and (have
since) challenged it with a semantic fog such as:

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?

EZNEC demonstrates the violation of your "beliefs," yes?

I miss Reg Edwards already :-(

Certainly you're a poor substitute for Punchinello. (and Kelvin is
winding up a pitch to wing a chunk of chalk off your noggin.)
