People often say common-mode current flows on the outside of the shield, while the current on the inside of the shield is always opposed by an equal but opposite current on the center conductor. This is because skin effect separates the inside and outside of the shield.

But if skin effect is isolating the inside and the outside of the shield, why would the inside-shield and center-conductor currents always be equal but opposite? IsIf skin effect makes the inside and outside of the shield distinct, why can't there be a common-mode current on the inside?

Can a common-mode current exist on the inside of a coax shield?
