Definition: for a homogeneous isotropic medium of substantially infinite thickness limited by a plane surface, the depth at which the electric field of a sinusoidal uniform plane wave penetrating the medium and propagating normally to its surface is attenuated in the ratio 1/e

NOTE – The penetration depth expressed in metres is equal to the reciprocal of the attenuation coefficient, expressed in neper per metre, in the medium that the wave penetrates.
