                 Calculate the inductance, resistance, and Q of a gold wire
                 above ground.

Assume a 1 mil bond wire 125 mils long and 50 mils above ground at a frequency of 10 GHz. Input data as "125,1,50,10" and press <Enter>.

Here is the output calculation for the gold bondwire:

                Inductance     =      2.954 nH
                Impedance     =      185.592 ohms
                Resistance     =      1.235 ohms
                Q                     =      150.318

Note: "Q" = Quality Factor
