An analytical method for calculation of total coupling coefficient between two helical resonators is presented. The ratio of electric to magnetic (EMR) coupling coefficient is calculated by approximating the electric and magnetic fields of the resonator with TE 10 and TM 10 spherical modes. A helical resonator is wounded to verify the analysis and simulation results.
