Physics.EE.skin_depth(omega, rho, mu=1.2566370614359173e-06, eps=8.85418781762039e-12)

Depth of the current layer in a conductor subject to AC fields::

J = J exp(-d/delta)

S

where J is the surface current density and delta is the skin depth::

S

Resistivity is defined so that the resistance of a bulk conductor is:

    rho
R = --- L
     A

where A is the cross-sectional area and L is the length.
