What did the Harvard experiment in Boston describe as the cause for
this? Some vague reference to an experiment somewhere does not show
anything. Provide a proper link if you want anyone to take the reference
seriously.

* *Intuition tells me that when using a perforated plate the lower the
frequency then the smaller the perforations in the shield to create a
blocking effect.
I believe this conflicts with your particle concepts. Why should hole
size have any effect on spinning particles of different frequencies?

You position also is in conflict with general understanding. If you are
correct, what hole size blocks very high frequencies. You concept would
result in a simple wire frame enclosure.

This would, I believe, opposes the progression of
skin depth with respect to frequency.
* * The books state for a mesh shield the perforations should be less
than 1/10 of a WL which on the surface opposes the results obtained by
the box experiment!
You may be ignoring the differences in the antennas. AM may have used a
ferrite loop, while FM may have been a whip. (We don't know because you
provide no details.)

Could one antenna be responding the magnetic component of the signal
more than the other? (We don't know because you provide no details.)

Is the difference involved with calculations
changes for sheets that are thinner than skin depth such as circuit
board traces or something else?
Type of materials, type of antenna, relative dimension may all play a
factor. You need to determine all of the effects that enter into the
situation and not focus on one or two.

Where has my intuition gone wrong in opposing the books?
Probably because you don't pay attention to the details and are relying
upon an understanding of the topic that is not correct.

Thanks for your response.
The article only gave me the given facts for the experiment and
nothing more.

If it is this article,http://www.fas.harvard.edu/~scidemos...sm/SkinDepth/S...
Then more was given.

It was an experiment in skin depth.
AM was significantly attenuated, too.
It specified the frequencies used and the associated skin depth.
The radio is also specified.

Your statement is correct

Using an extremely cheap radio as a measurement tool is not sound
technically.
Could be but that is what they used.



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. 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.
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!
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.
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. 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.
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.
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.
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.

With respect to receive of the radio. Since the foil is flat and
without perforation it should be sensitive to everything thrown at it.

But the experiment in question is about skin depth which does vary with
frequency.

Unless, of course, you are talking about some other Harvard article, but
we only have to guess, because you still don't identify it.

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.
If we accept the above then we have agreement with

Only because you interpret it that way. The article does not mention

mentioned.

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.

Which of these antenna programs have you analyzed to the level to make

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.

Ok so you are not interested in a debate. I thought that as a newby
you might just be a little uncomfortable with the idea of using
Quantum theory if you desire particles or to use classical physics if
you desire waves. Obviously it is very difficult to accept change.

Joe, I wanted a debate as to why adding a time varying field to a
boundary enclosed static particles in equilibrium is illegal. This is
in opposition to what the books say.
My whole theory lives or dies on how this is resolved. Nobody will
provide technical details as to why this is illegal. I supplied what I
believe supports the idea but nothing can be considered "proof" to
those who oppose change. If computer programs support retaining
equilibrium at all times then that is an independent result. If
Quantum physics chooses
particles over waves again that is an independent result which
questions conventional judgement. To accelerate a charge in the form
of a wave is un explainable in present science.Nor is the division of
same explainable with respect to the Faraday cage,
To provide an accelleration mass is a must but how a wave provides
such is stated no where. All of these in my mind questions the
validity of using boundary laws for which one
must also reflect equilibrium i.e. is it illegal? Why is it illegal?
It does follow the laws of Newton therefore Newtons laws are at
risk.Yes we are talking about the movement of flux
but movement requires the addition of time. So again the salient point
in this debate is the
addition of a time varying field to an arbitrary boundary containing
static particles deviate from the requirement of equilibrium in all
laws. Namely all statistics are placed on one side
of an equation that equals zero is a specific requirement. "Equal"
really means "equal" and not close enough for horse shoes.
For any sort of debate this central question must be resolved at the
beginning or there is no debate. Resolving this allows for progress
into other areas all of which depends on the above question. If nobody
can demonstrate why it is illegal then proof or truth is not
attainable. If we cannot debate technicalities of radiation then the
group is left to exchanging insults and spam or poll counting

Joe, I wanted a debate as to why adding a time varying field to a

your whole concept is malformed. if the 'static particles' are in
'equilibrium' (i.e. not moving) and then you add a time varying field
the particles are going to start moving and won't be in equilibrium
any more... assuming of course the particles are charged or have a
magnetic moment.

This is in opposition to what the books say.

which books. quote titles and paragraphs and what you think you
oppose in them. i have given you my quotes as to why it is not
necessary to add a time parameter to gauss's law and you ignore it.

My whole theory lives or dies on how this is resolved. Nobody will
provide technical details as to why this is illegal.

then you better start hunting for a new theory. i have provided you
formulas in the past and you have ignored them... personally i don't
think you even understand the concepts and have probably ignored me on
purpose just so you can continue to blather on to get more attention.
