I have spent a considerable amount of time in researching the above
subject
as a result of some comments made regarding Gauss's law of Statics
and its connection to the above Poynting's Vector. I have not yet
found
a description of an actual proof similar to described by the Gaussian
Antenna
and have found a number considerable number of " attempts" to provide
such a proof on the internet. But as yet none have been found as
substantial
as a clustered radiated elements in equilibrium.
What I did find was a indepth explanation of electro magnetism by
Harvey
on the net that discusses antenna radiation from it's beginnings
together
with past untruths that are put under the microscope. These papers may
not
be equal to what is presently understood by scholars but never the
less
I thought I would share it with the antenna and radiation minded
people
of this group.. If somebody knows of the existence of a real time
proof
of Poynting's Vector i.e by a bench experiment I would apreaciate a
pointer to where it can be seen
Ofcourse if there are some comments to be made on the Harvey papers
this would be a good place to put them.

the Poynting vector is nothing but a way to represent power in 3 dimensions.
That is it, nothing more, no magic, nothing worth proving, just a simple
statement of energy flowing through a surface. Now if you could prove it
wrong that might be interesting, but otherwise it follows directly from
conservation of energy and obeys all the related laws.- Hide quoted text -

But David, you reject the basics of a Gaussian antenna which is why I
have reservations about your logic tho granted others appear to
agree with you, so I want to read up on it for myself.
When reseaching the net I see numorous attempts to
provide a real time proof for it but nothing as factual as the
Gaussian antenna.So contrary to what you say there is a lot going on
in trying to find a proof for it even tho you at the same time reject
the Gaussian connection. After seeing the automatic rejection of
ANY ideas that represent new ideas in the amateur community I am
beginning to wonder if the E/H antennas is a victim of the same
syndrome . I am coming across many papers that suggest that there
is more to radiation than scholars presently believe so it is
natural to me that amateurs would automatically reject any new
aproach by derisive comments such as junk science or similar.
What does come thru is that members of this newsgroup state that
the Gaussian antenna has already been invented but fail to point
out the paper on it. Stating that Maxwell provided a connection
by mathematics of the E and H fields is not enough to provide
proof and certainly not without introducing the Gaussian
connection so its use can be seen and verified.
If it has actually been pre invented then there must be a
paper conecting Poynting's vector and Gaussian statics law in
existence rather than a conoctation in mathematics alone but
without qualification, and certainly a reference to it in
Jasik or Krauss. However, members have failed to point out
such a reference where normally they always point to old books
on the subject. It is for this reason I am looking for a
real time proof of the Poynting's Vector because not only
for the mathematical aproach but also for its connection to
Poynting which you for one reject out of hand because of
some gut feeling. If faced with the same problem I have
no doubt you would procede the same way.
