Bear in mind that current flowing in a conductor will always generate a

always generate a radiating electromagnetic field. That radiating field
will convey energy if it is not nulled by another equal and opposite
field. You need to demonstrate that all the fields resulting from all
the currents are nulled in this scenario.

It is true by definition for ideal coaxial feedlines in which the
radiating fields are 100% nulled by the basic shielded design, i.e.
solid copper outer tubing much thicker than the skin effect depth.
The problem with the program is that the conclusions violate the
conservation of energy principle. It is simply impossible to have
a coax SWR of 1400:1 while radiating 99.9% of the power from the
feedline.
