F A N T C is a JavaScript interface pulling in the power and versatility of G E O T C, a library of functions for computing reactances formulated and coded in JavaScript by Paul Nicholson. Although G E O T C applies some techniques used by T S S P software, it should not be confused with T S S P software.

To learn more about the core functions of FANTC, visit G E O T C.
To view the latest research on the physics of Tesla Coils, visit the Tesla Secondary Simulation Project.

I would like to say thanks to the team of coilers who have provided invaluable and sometimes difficult measurements for the TSSP, whereby, the evaluated data produces a better understanding of Tesla Coil physics. I would also like to say a special thanks to Paul Nicholson and Terry Fritz for their dedication and invaluable research on the physics of Tesla Coils.


    Remember when the following was only a fantasy?
  • Calculation of the capacitance of spheres, toroids, coils, discs and cylinders, in free space, or in-situ with other components.
  • Calculation of self and mutual inductances.
  • Calculation of distributed reactances, effective lumped reactances, and resonant frequencies.
  • Calculation of voltage and current profiles.
    not any more!
