Hi Arthur,

Very interesting assumption. I suppose (and that is always a risk
with a renowned theoretician such as yourself) that you have an
instrument that can detect the difference in radiation between a solid
wire and a tubular one - all other externalities being the same?

No, I suppose not. You've been burnt too many times with your own
results confounding your expectations. However, putting that grief
aside (and it must be a terrible burden to endure), if a hollow
element were filled with a custard center so that it was in
equilibrium, would it radiate?

The material is diamagnetic which means that it has the ability to
levitate particles of like form. Levitation is the result of a
particle
escaping from its immediate gravitational pull and where it can exist
unharmed by surrounding gravitational action which by its very nature
has voids in gravitational action. In the case of a Gaussian
field that means to escape to beyond the arbitary border.
It is this very movement of particles without regard to gravitational
forces that allows for straight line actions inspite of the spherical
surface of the earth
Where material is solid then the internal surfaces of the skin depth
which is also the external surface of current flow cannot levitate any
part of the intervening structure.
Levitation is created by a magnetic field where escape from the parent
structure is possible.On the inside levitation since particles
concerned
are part and parcel of the material without freedom levitation is not
possible.
By the same token inductance and capacitance cannot exist on the
internal
path since another skin depth cannot exist.

If a radiator is made of a tube of minimal thickness with respect to
skin
depth and the ends filled with the same diamagnetic
material where a fuse connects them, the fuse will blow when RF is
applied to the external surface
