Calculator for Skin Effect Depth

Calculates the effective skin depth (1/ε) 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 ρ = Is the resistivity of the conductor in Ω/m

f= frequency in Hertz

μ = Is the absolute magnetic permeability of the conductor

The absolute magnetic permeability (μ) = μo x μr

μo = 4π 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 ρ are from CRC Handbook of Chemistry and Physics 1st Student Edition 1998 page F-88 and are for high purity elements at 20°C.
