In the field of microwave engineering, skin effect is referred to when people talk about the fact that current, that is, electrons only flows on the surface of transmission lines, e.g. microstrip lines.
I've checked many EM books--everywhere skin effect is demonstrated with both E and H
parallel to the surface of a conductor, with the wave propagating into the conductor.
Now here is a gap between these two. For transmission lines, waves actually propagate in the direction parallel to the line instead of perpendicular to conductors. And if we draw the field lines, most of them lie in the surrounding dielectric materials instead of in the conductor.
Can anyone help me bring these two together?
