In your plot how are you defining S, the spacing between conductors?  Is it 
center to center?  Is it consistent for both the approximated and actual 
curves?  It appears that only the actual curve uses the center to center 
definition; in the limit as S-->d  the inner edge to inner edge spacing goes to 
zero, and Zo also goes to zero.
