<p>such a current; this explains the attenuation of electromagnetic waves in metals. Although the term skin effect is most often associated with applications involving transmission of electric currents, skin depth also describes the exponential decay of the electric and magnetic fields, as well as the density of induced currents, inside a bulk material when a <a href="page.php?w=plane_wave">plane wave</a> impinges on it at <a href="page.php?w=normal_%28geometry%29">normal incidence</a>.</p>
