WebSkin depth ( δ) defines the propagation distance at which the amplitude of an electromagnetic wave is reduced by a factor of 1 / e; i.e. reduced to 37% of its original amplitude. Skin depth determines the penetration depth for GPR systems. The skin depth is given by: δ = 2 ω 2 μ ε [ ( 1 + ( σ ω ε) 2) − 1 / 2 − 1] 1 / 2.
