Akt. Assis, On the propagation of electromagnetic signals in wires and coaxial cables according to Weber's electrodynamics, FOUND PHYS, 30(7), 2000, pp. 1107-1121
We derive the equation describing the flow of a variable current in straigh
t wires and in coaxial cables from Newton's second law of motion plus Weber
's electro-dynamics. We show that in both cases the signal propagates at li
ght velocity.
