Calculates the Inductance of a single round wire of common conducting materials using the formula and data referenced below.
From Transmission Line Design Handbook by Brian C Wadell, Artech House 1991 page 382 paragraph 188.8.131.52
The self inductance of a straight wire at high frequency is:
Where d is the diameter in cm
l is the Length in cm
f is the Frequency in Hz
The formula originates from Inductance Calculations by F W Grover, Van Nostrand, Princeton, NJ, 1947, Reprinted by Dover Publications, NY, 1962. Two more formulas are given by Brian Wadell for calculating T(x) which are "accurate to a few percent over the range 0.0 ≤ x ≤ 100.0".
r is the radius of the conductor in cm
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 and σ are from Transmission Line Design Handbook by Brian C Wadell, Artech House 1991 Table 9.3.2 page 446.
