Skin Effect vs Skin Depth

This page on skin effect vs skin depth describes difference between skin effect and skin depth.

As we are aware that at microwave frequency wavelegth is very small and hence lumped electronic components do not work at such lower wavelegth. This is due to following reasons.
•   components size and lead length is considerable.
•   L and C values become significant at microwave frequencies.
•   Skin Effect

skin depth

Skin effect usually refers to the situation where in alternating current(AC) flow concentrate on the surface of the conductor. DC currents flow on the entire cross section of the conductor.

As mentioned in the equation, skin depth is the function of frequency,permiability(μ) and conductivity(σ).
