It can be thought of as an explanation for why a person is safe inside a metal car if lightning strikes.
This effect is associated with an impedance that grows at high frequencies. One way to deal with this is to use bundles of conductors woven together with insulation between them, which is known as a Litz bundle. It arises from exponentially decaying solutions to Maxwell's equations. The associated length scale goes like the square root of the resistivity and the inverse square root of the signal frequency.

FTP, what is this effect, in which an alternating electric current tends to flow near the surface of a conductor?
