I am reading a paper in which it is maintained that VOP in a non-inductively wound conductor is infinite, based on the use of the formula:
VOP=C / √ue
where C is the vacuum velocity of light, u is magnetic permeability, and e is dielectric constant.
It is maintained that when u or e is zero, the VOP is infinite, and in a non-inductively wound conductor, u is shown to be zero due to cancellation of induced magnetic fields in the windings of the conductor.
I have only seen the formula:
VOP=C / √e
in my rather limited reading.
Should the permeability be in there or not, and if so why is it sometimes omitted?
Can anyone shed any light on this?
