This week end is going to be wet and cold, so I thought I would give
you a radiator to play with if you are willing to make something for
yourself.
Get yourself a piece of aluminum mesh used for window insect stopping
entering your house. Soak this piece of mesh in some watered down
muriatic acid (approx $5 a bottle at a hardware store This is to
remove the insulating coating so it becomes conductive. Now this mesh
is woven so it helps to compress the strands together by tapping with
a hammer. Connect a MFJ259B to the base corners and scan to see where
the resonant frequency is.
I used a 8" x5" piece of mesh and it was resonant from about 110 to
140
MHZ so it is quite broad banded and easy to find the resonance The
vertical strands carry the applied current and the capacitance square
holes in between is a electrostatic field around which the
displacement current flows. What you have, basically, is a *full wave
dipole folded very closely upon itself to form a closed circuit with a
low impedance. This is basically a transmission line if the ends are
open. The cross jumpers take the place of *dielectric spacers that are
present on a open transmission line so that they may enclose an
electrostatic field created by the displacement current. The vertical
strands are really in series ,so you have effectively placed a long
length of wire into a small volume which you may shape into any form.
To play with this further, place it above a conductive sheet and note
the changes. Then try pinning it together into a cylinder and note the
changes.
Have fun playing with it.
Looking at the physics side of things. When a particle is generated by
the Sun it goes to the border and even tho it is extremely small it
breaks the border by applying a straight force vector together with a
circular vector. This same combination repeats itself when current is
applied to a radiator which also produces a circular current. These
same vectors are later repeated with gravity in combination with
rotation all of which are per laws of Newton. The particles that
escape from the sun sheath conductive materials on Earth. This is
explained by making the Gaussian field for statics a dynamic one so
that it becomes the same as Maxwells laws. The combination of fields
from the applied current when intersecting the electrostatic field
dislodges particles by elevation with spin while accellerating to the
maximum speed which is that of light so the particle can take on a
straight line trajectory with spin where the Gravity vector is
cancelled.

Since you're lecturing on physics, as I said before, you should post this to
sci.physics and sci.physics.research and see what they think.

Why? Hams will deny it without trying. Physics! all will deny it as it
comes from an engineer.
Somewhere in between some one will try it. Then curiousity will take
over and the question will be asked " Why is this" And then the
naysayers will answer" you didn't measure it correctly or the MFJ 259B
was not intended for that" Then a person with a small garden will get
a bigger piece to try it out on Top Band. "You have to prove it" say
the naysayers
together with " you are an engineer so you can know nothing of
physics" "Well I just followed Einstein" I said " He was convinced
that the secret of the weak force lies with radiation" So you are
comparing yourself with Einstein?" said the naysayers. So I said that
"Gauss showed the way with the static field to which I made dynamic
and added radiators
so that it became the same as Maxwells law since I maintained
equilibrium!"
":You can't do that" said the naysayers " that is not in any of the
physics books" ":I know "
I said " be patient ": What you seek you will find" . Now who is the
next person to argue with Einstein and his prediction? Newton stated
that every action has an equal and opposite reaction. The big bang
started from inside a arbitrary boundary. Equilibrium was broken when
the smallest of particles from the Sun ventured towards the boundary.
When this happened that little of little particle became an opposing
force which was off centre from the opposite force such that it also
applied a torque vector (spin). That chain of force vectors end with
the combination of gravity with the rotation vector of Earth, where
the chain of events passed along the phenomina of radiation as
predicted by Einstein. No. I am certainly not going to argue with
Einstein. PS try it for yourself with the many computer programs so
you can argue that the programs are wrong where only the vendor is
left to argue against. Now you have a bigger question, How does a
particle propagate while neutralizing gravity?. Ponder on that for a
while. Now for the biggy Will Cern change there minds when they read
this? No we are going to find the Higgs field that nobody has found
even if we have to blow up the tunnel. We want five forces to make up
the Standard Model so we can go down in history!
