Re: Neat technology/concept Oh... hrm, I guess I'm still not understanding it. Time for me to find a cross-section diagram of what the dielectric portion is, vs. conduit vs. copper/core...

Time for me to find a cross-section diagram of what the dielectric portion is, vs. conduit vs. copper/core... take a pair of snips to a leftover piece of coax. you have your center conductor (that protrudes from the fitting), then a "spongy" stubstance, then an outer jacket of some sort of metal and then some sort of outside wrapping/dressing.
the dielectric actually carries the wave. in the purely transverse electromagnetic (tem) case of wave propagation, you have a voltage differential between conductors, resulting in a electric (e) and magnetic (h) fields that obey maxwell's equations. when excited, these fields will allow for a propagation down the coaxial cable in the low-loss dielectric material according to the helmholtz wave equations.
