Greetings,

You'll find this on my site http://www.alansharp.co.uk  under Maths and
Theory.  

But such a squat coil would not be optimal - it would breakdown because of
a high volts per turn ratio.
We also want to minimise the self capacitance of the coil - when this is
taken into account it turns out that for maximum Q the height should equal
the coil diameter.  But such a squat coil would not be optimal - it would
breakdown because of a high volts per turn ratio. 

Alan Sharp,

The author proofs, that coils with an aspect ratio length/diameter of 
0.45 provide maximal inductance and minimal resistance.
