Default Real time proof of Poyntings vector


"art" wrote in message
ups.com...
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.
