Skin effect
High-frequency conductors

The skin effect appears in metal at very specific frequencies. A metal behaves in three different ways, depending on the frequency. There is the conduction range, which is of primary concern to electronics engineers, the relaxation range for infrared and optical frequencies, and the transmission range for ultraviolet frequencies.

In the general case, the equation (1) , with the expression (2) in harmonic operation, results in :...
