Spiral Capacitance

I have a set of spiral electrodes that I modeled using MathCad to help me develope a way to calculate the total capacitance. I'd welcome the collabs help to determine a better, more accurate solution.

I tried two methods:

1) Using an example from my old calculus book, i determined the length of the spiral and simply calculated the capacitance of two plates.

2) Taking a section of the assembly and treating each turn of the spiral as a cylinder and used the capacitance calculation of two cylinders (as a start) form my old physics book.

Old books are great!

I look forward to alternative solutions to determine the total capacitance.

Sincerely,

Norm
