"Small skin depth" Impedance Boundary Condition

[Fernando Seco <fseco@xxxxxxxxxxx>]

Hi David & FEMM people,

When you discuss Boundary Properties in the FEMM User's
Manual and you come to the Small Skin Depth, it is stated that:

dA/dn + (1+j)/delta * A = 0 (eq 19)

I feel that it should be:

dA/dn + (1+j)/(mur*delta) * A = 0,

with mur = mu(metal)/mu0 being the relative permeability of the
metal. This comes from the continuity of the tangential component
of the magnetic intensity, Ht.

How do you feel about it? Greetings from Spain,
