Actually, I should have said magnetic fields, not electric
fields. The E-field inside a conductor is 0 because the
charges move to cancel out any E field; it's the mag field
that stores the energy and moves the charges, and that moves
the charges in a "good" conductor. And it's the mag field
that gets damped out inside the conductor.
I thought I better correct that before someone else did!
