Abstract
A method of wirelessly transmitting power or data is disclosed. The method may include the step of providing a transmitter including a driver coil and a first transmitter resonator coil. The driver coil may have a driver coil resonance frequency, and the first transmitter coil may have a first transmitter resonator coil resonance frequency. The method may further include the step of providing a receiver including a load coil having a load coil resonance frequency. Furthermore, the method may include tuning the first transmitter coil resonance frequency to be higher than both of the driver coil resonance frequency and the load coil resonance frequency.
