The particle wave duality of electromagnetic waves was settled back in the
1930's and further refinements have only gone on to prove that
electromagnetic waves act as both particles and waves depending on
circumstances and measurement. There is nothing wrong in considering the
generation of an electromagnetic wave using particles, so long as the end
results are in agreement with measurements taken using standard scientific
equipment.
Also agreed with except for radio waves that if duality over the whole
spectrum is true it is not so with radio frequencies. Gauss makes it
quite clear that *static particles can become a dynamic field
according to Maxwells equations. If they become waves at the higher
end of the frequency span say beyond X rays it is of no concern to the
subject of radiation in the amateur bands which is the field that I am
working with.
there is no exception for radio waves, they act as photon particles
also, just like the ones at visible light frequencies and higher. this
too has been accepted for many years.
David, I won't fight you but I would like to take advantage of your
expertise. The question whether you may make a gaussian field dynamic
such that Maxwells equations can be used is the beginning of this saga
as the group will not accept it.
So I will move on to the Faraday cage.
*There is an animation of what exactly happens on the web with respect
to radio, you may want to look it up.
But for openers you would get my attention in explaning this phenomina
with the use of waves instead of the actions of mass or a particle.
This is a sincere request as it seems discussion of duallity means
talking past each other when there is a clear difference between the
action of waves and those of particles,namely attraction. versus
cancellation.
You supplying this may get the subject back to a level plane of
politeness where the postings will supply enlightment instead of
derision.
Thanks for reading

duality applies to all frequencies of electromagnetic waves and
photons... it all depends on which is more useful for whatever you are
working on. *particle physicists like photons because they can draw
them in feynman diagrams nicely and they like to talk about them
getting absorbed and emitted by valence electrons, engineers generally
prefer waves and fields because they are easy to calculate over
macroscopic distances using maxwell's equations.
and i still say your extension of a time parameter in gauss's equation
is unnecessary since the equation applies at all times. *just because
no 't' shows in the equation doesn't mean it is necessarily static,
just that it is not an explicit function of time. *actually if you
study all 4 of maxwell's equations closely you will see that NONE of
them are explicit functions of time. *two of them do contain
derivitives with respect to time, but none of them contains 't' as an
independent variable.
One short point. Time is omitted because it is based on equilibrium
alone where nothing is happening and all is balanced The Big bang was
the instance that time began and equilibrium is broken by movement or
energy exchange. It is the energy exchange subject which alone gives
us the picture of change without which there is nothing.
no, time is omitted because it is irrelevant to an equation that
applies 'at each instant' in time. *so at any instant you can add up
the charges inside the gaussian surface and know the total flux
through the surface. *the only 'equilibrium' is the equals sign that
states that the total flux is equal to a function of the total
charge. *you can indeed have energy flow across the gaussian surface
and the equals sign still applies at every instant in time.
David
Well that is a good opening or introduction, tho I wish you had not
mentioned your thought of adding time to Maxwell as the response to
that was explosive years ago. I hope that others will put that aside
so we can concentrate on the main thrust of the problem.
but what is the 'problem'. *maxwell's equations as published for the
last hundred years or more seem to work just fine to the limits of our
measurement capabilities.
I will be very interested in what you will use as the subject for
explanations to how *the wave actually works. From the above, I really
believe you have the background or track record to explain all and how
things are working to the satisfaction of all. This could be exciting
Regards

No one knows how the wave 'actually' works, but we have maxwell's
equations to tell us how to accurately model and predict configuratio
of fields and the propagation of waves. *That is the one thing your
'theory' seems to be missing, in order for you to have a theory worth
discussing it must first be put down in equations that describe
something measurable so it can be verified versus reality... AND then
it must predict something different from all other existing laws and
theories.
O.K David Let us look at the Faraday cage or better still a shield.
Faraday has shown that when one side is impinged upon by a ":wave"
that it will separate into two components of "waves or fields". They
will not stay as one but will separate into two separate energies or
charges
On one side of the conductor (electric field) and the other field
will follow (magnetic) on the other side of the conductor. The time
elapsed is equal to half a cycle or half a period of the frequency
applied.
During the next half cycle the charges as they are now on each side of
the conductor are drawn opposite to each other with the conductor
inbetween.
Thus this second half of the cycle of time is taken up by movement or
an accelleration of the charge inside the shield until it is exactly
opposite(and equal) to the outside charge. The intenal charge has to
move because it is out of phase with respect to the external charge
thus it is forced to accelerate or decellerate if you will to its new
position or resting place. While this internal charge is moving the
flux that it is carrying is transformed into a time varying current
such that the charge is now without energy and static and its energy
in the form of a time varying current has moved on outside of the so
called boundary in the same way it in initially entered our boundary.
Thus at this point we have located the where abouts of all energies
involved by adding all the "instances" of time ( dy/dx ) until the
instances added up to a period of time for the frequency applied.
At all times where the energies are at rest there is no accelleration
and the energies dissapate into another form or state.
As you can see David I have concentrated on energy asd opposed to its
form where we applied an energy at the transmitter where it was
reciprocated at the receiver. Mention of waves or particles have been
deliberatly avoided and we have accounted for all forces or energies
involved for a cycle.
Now we do not have to let it rest there.We have Maxwells equations for
radiation and with todays computors that same equation can be oriented
such that if you input a radiator it will change the input to the
metrics of Maxwells equations which is a wavelength to satisfy
equilibrium. Thus the program only accepts input metrics that are
included in Maxwells equations such that equilibrium is adhered to at
all times
When applying a radiator to such a computer program it will supply a
accountability of all forces that follows the intents of Maxwell.
Thus when the program has done its stuff it will supply a full
accountability in terms of 100 percent,
Thus I have supplied a sequence of "observables" that relate to the
experimental results of Faraday. I then applied the same situation to
the accepted Maxwell mathematical equations which also provided 100%
accountability.
Both of these approaches result as equals. To satisfy those who have
positions of duallity I have used energy terms alone without the
description of its carriers.
So David, I have provided all for your dissemination, where you can
break it up into scientific parts for comment including desired
additions required to fortify a position. It is rather long and
detailed but in no way can it be seen as "hand waving". At least you
seem to be alone in sticking to physics without being dominated by
emotions.
One can easily hang a piece of mesh and connect it both to the ground
and a radio and both charges will take a separate path since they are
divided by a conductor into two separate entities.
Best regards
Art
