Hi Bart,

After looking at the Fraga equation again, it does look and L and C 
directly. It uses the product of L and C by virtue of the frequency 
needed for skin depth.  Your Les and Ces are the frequency 
determining equivalents that are suppose to be accurate to like 
1%.  How accurate are Medhurst C and Wheeler L in predicting the 
correct frequency.  I doubt there will be any significant difference 
especially since f gets sqrt'd which will cut the error in half.
