This i do not understand. Do you mean mutual inductance??
What is the coupling constant?? what are its values range??

>overall induction of the secondary (how are you going to calculate it?)

I have already derrived a formula for a general case of this shape in
algebraic form. The maths theory is not a problem here!

>will self induction and self capacitance issues arise from the design?

Is there any way to account for this?I mean, calculating the expected self
inductance and capacitance??I never though of this as a problem.
Thankyou for reply. Any more ideas/questions/sugestions/facts welcome.
mark.
