Differential Impedance of Stripline

THESE FORMULAS ARE APPROXIMATIONS!
They should not be used when a high degree of accuracy is required.
The approximate formulas are provided along with restrictions on the relative size of the various parameters.

All the units are in SI (Iternational System):
[m] = meter
[s] = second
[H] = Henry
[F] = Farad
