Default Radiation penetration/absorbtion

Yes my concepts on radiation are in opposition to the
norm so I am using the facts presented as a way of destructing or
confirming my perceptions.
When I read up on Faraday shields the concept of "particles"
predominates as opposed to "waves" without exception and I am trying
to make some sense of these differences when considering propagation.

Perhaps it is a problem with how you do searches. On this pagehttp://en.wikipedia.org/wiki/Faraday_cage
There is no mention of particles as the means of transport to the
shield. Electrons are mentioned as they are part of the cage and respond
to applied fields.

Yes they clearly state electrons which is a particle.


But the electron is NOT how the signal gets to the shield. You need to
read more carefully.


It is extremely
small and of minimul mass which is why Einstein states that the speed
of light is a maximum.
The article you point to shows charges or fields which must be carried
by something like particles as proven in other theories such as
Quantum theory.
Fields and waves book by Ramo etc constantly lean on boundary laws
thru out there book and boundary laws clearly state the relationship
of static particles to equations relative to radiation.
If we are to refer to waves then accelleration demands mass so we need
a connection between waves and mass.


Try thinking in terms of fields and charges.


Assuming it is a wave that impinges on a Faraday cage we then have to
determine what half a charge comes about so that the charge cancels
and thus reverts to a time varying current. Again another puzzle!


A puzzle because you apply your misconceptions BEFORE first
understanding what is there.


Anyway the article that you point to shows a point charge which is
certainly not a wave which would be represented by a line of the
length used in top band.


Only because you interpret it that way. The article does not mention
point charge as causing the behavior, externally applied fields are
mentioned.

As far as penetration goes the mass involved is always of the same
mass and ikt is only the charge that varies in frequency as shown by
the radius of spin in helical form of the charge.Thus again we have to
find a connection between wavelength and charge.Another obstical....



If you can point out why one cannot use boundary rules so that
particles are recognised as the carriers of charge the same as with
Quantum theory I would be very gratified.


Gauss' laws refer to flux and do not require carriers of charge to exist.

None of the group excepting
newcomers such as your self has provided proof of the inelligability
of my approach so I am forced to explore other facets
of radiation to determine why my aproach is in error.


A lot of that has to do with your inability to communicate adequately.

I apologise for not being clear in the subject that creats problems
for newcomers such as yourself but to re iterate the discussion which
has been going on for years would be quite a hardship. However if as
a newcomer you can supply why static particles cannot be associated
with propergation you would be doing something different to the group
that are relying on zero facts and replacing it with insult and spam.


If you are trying to present a new concept, then it is up to you to show
why, and that, it is right. Do that in a clear convincing way, with the
appropriate math, and you might foster a worthwhile discussion.

The wrong way to do this is throw a half-baked idea out and expect
others to accept it. You'll never prove a point that way.


Thanks for responding in a sensible way .



I would like to point out in
addition that existing antenna programs with optimizer based on
Maxwells equations rely very heavily on the maintenance of equilibrium
which is the foundation of my aproach which includes particles and
certainly not waves.


Which of these antenna programs have you analyzed to the level to make
this statement? Have you looked at the source code of the programs?

If we are going to throw out such programs we surely must know why
before we take such a step when the presence of particles appear to be
in the majority of aproaches.


Why throw out the programs? Using waves is perfectly correct and
adequate for them.

Waves provide an adequate model for propagation. Particles may be
adequate at the quantum level. Both are ways to describe something.
Neither may adequately describe thing in all cases. They are models for
what happens. As long as the models are applied appropriately, there is
no problem. Applying a model inappropriately is bound to cause problems.

How do you expect us to know what you are really talking about?

I am fully aware that I am not clear with my questions but I have to
live with that.
The point is that I am still trying to find out why the group does not
accept the extension of a static field in equilibrium cannot be
connected to Maxwells equations when adding a time varying field a
train of thought covered by boundary rules that are used in many
places.


That is solely because YOU can't describe your concepts adequately.
Putting "+t" on both sides of an equation does not necessarily lead to
anything meaningful. IF you were to describe your thoughts adequately,
perhaps someone would show you where you make errors.


If we accept the above then we have agreement with
