Calculator for Skin Effect Depth
Calculates the effective skin depth (1/e) for common conducting materials using the formula and data referenced below .
From Transmission Lines and Networks by Walter C. Johnson, McGraw-Hill 1963 p58.
Nominal depth of penetration for a conductor
Where ? = Is the resisitivity of the conductor in O/m
f= frequency in Hertz
&nbs p; µ = Is the absolute magnetic permeability of the conductor
The absolute magnetic permeability (µ) = µo x µr
µo = 4p x 10-7 H/m
The values for µr are from Transmission Line Design Handbook by Brian C Wadell, Artech House 1991 Table 9.3.2 page 446.
The values for ? are from CRC Handbook of Chemistry and Physics 1st Student Edition 1998 page F-88 and are for high purity elements at 20°C.
