Hello Dale, Thank you for the reply. But I am talking about the ideal case where the cable has infinite conductivity and progpagation is pure TEM wave, which makes it sure that there is no "longitudinal" (i.e Ez=0) along the cable by definition. In this case, what force acts on the charges to...

Every physics books show that wave prograpation in coxial cable is TEM wave, like in the picture. But we know that J=σ E from ohms law, which says current in same direction with E field, which is not the case here. What do you think the reason is ?
