Art, the link below leads to empirical proof that such reflections
exist.

don't confuse him with facts, especially facts out of books... they are all
out of date since they don't have his latest theories included in them.


If graphs of current flow is to be generated it must provide a graph
of the lead edge of the current to compare with the trailing edge at
an instant of time, because it is a time varing current.

For a fractional wave antenna skin depth or resistance on the surface
does not disappear until the trailing edge of the RF pulse reaches the
antenna top. In the mean time current rises at the top as the fields
collapse which means that the lead current is prevented from turning
around because skin resistance is still being maintained Thus it has
no other choice to pursue a closed circuit other than travel on the
inside of the radiator and being shielded by the surface eddy currents
produced by the trailing current end.
If by some phenoma the current was able to flow down the outside of
the radiator it must also produce eddy current which thus allows for
radiation from what originaly was a puise to a duallity of current
flow, each of which creating radiation without frequency remaining
constant.
There is no reasonable reason to depart from the closed circuit ideals
to manufacture an incomplete sequence of events not supported by
science but printed in books. Otherwise there will be no progress in
the understanding of radiation until the actions of eddy current or
the weak force is fully understood with its ejection of particles from
diamagnetic materials.
I will not add to this thread as it is surround by closed minds of the
aged.
Have a great day
