Inductance / Quality Factor formula

I am interested to find out the inductance and quality factor of an inductor by designing a trace of metal and then doing EM simulation in ADS using two ports. For this I found one formula for finding Zdiff as:

Zdiff = [Z(1,1) + Z(2,2)] - [Z(1,2) + Z(2,1)]

and then using Qdiff = (Zdiff)/(real(Zdiff) to find quality factor.

Can any one please help and guide me from where the Zdiff equation is derives.

Thank you
