Waves and Boundary Problems
Although a static conductor is characterized by E = 0, the electric field E can penetrate into a conducting medium if it is varying as a function of time. In a conductor, charge carriers are mobilized by an applied electric field so that currents flow through a conductor under time-dependent conditions. Distributed currents, called eddy currents, flow at high densities in the close vicinity of surfaces to certain depth, called the spin-depth. In free space, electromagnetic waves are reflected by dielectric boundaries as well as conducting surfaces where surface currents play a significant role.
