Most would likely enjoy Kraus` story of his invention of the axial-mode
helix in his 3rd edition of "Antennas". This is a choice book!

I have his second edition and I find no mention of radiation from the
beginning where current is applied onwards. Have you found anything
that can
contribute other than empirical grounds? You have avoided the question
so far

Hello Art,

Radiation from accelerating charge is fully understood (from theory
and verified practically), hence antenna theory. When you take the
complete formula for fields (near and far) generated by a short wire
segment (hertzian dipole), you can calculate the far and near field
(magnitude, orientation, phase, etc) from every construction. The only
problem is that you have to know the current distribution in your
construction.

It is not of interest whether the charge is excited by just a voltage
source or EM radiation (like in reflection of waves on conductors and
dielectrics). This is done in many FEM programs.

Of course in many practical circumstances it is easier to use the
"laws" from other people (that are derived from basic theory). One of
the results are the Fresnel formulas for reflection.

When you know the properties of the soil at the operating frequency,
you can calculate the complex surface impedance and hence the complex
reflection coefficient.

Just mentioning words as "curl", "vector", "Gaussian" etc, doesn't
make sense without further information.

Earlier I explained that the gaussian law can be expanded to provide a
link to a radiator. The mathematics has been provenon this newsgroup.
Unfortunately only one person accepted that proof. Using this new
aproach,thesis or what have you provided for the generation of arrays
where all radiator were resonant which provides specific advantages.
It also provides for multiple arrangements of elements for maximum
gain by virtue of the condition that equilibrium must be maintained in
the enclosed volume of a standard Gaussian field which means that more
than one arrangement of a given number of radiating elements can be
arrived at for maximum gain.
Thus not only was the theory proved by mathematics in accordance with
known laws it has also been overchecked by the use of the equilibrium
condition which was imposed as well as all being confirmed by accepted
computor programs. Since all new theorem are immediately rejected by
the vast majority of this group but with one exception from down under
you surely can understand the futility of convincing people until they
see it written in a book because of their lack of individual thought.
One thing I have proved to my satisfaction that many who perceived
themselves as experts have shown quite clearly that they have over
estimated their abilities.
When my work is published it will not only be seen that many were
unable to think on the basis of there own knoweledge but also their
knowledge of Electrical laws were flawed. That was my intention to
prove when I introduced extension of known laws on this newsgroup plus
the exposure to all of the residing pseudo experts. Time will tell
that I have suceeded
in my mission

I am one who missed Art`s explanation. I am curious as Gauss and
antennas have not been directly related in my mind.

Wikipedia says:
"The total of electric flux out of a closed surface is equal to the
charge divided by the permittivity."

J.C. Maxwell may have found Gauss useful, but why do I need him in
amateur antenna wotk?

If you add time to both sides of the Gaussian law you have the
connection
which is more specific than that stated in Maxwell laws .Specific
means the shape of the radiating cluster in question upto and
including resulting radiation desirables. A quick search on "Gaussian"
will bring you upto date
All have been extensively stated.
