Abstract :
The optimal designs are investigated for a wireless resonant energy link (WREL) based on a nonradiative magnetic field. Internal resistance of coils is considered in relation to the coil configuration. As a result, the designs are obtained for the transmission efficiency maximum or for the effective power supply maximum. In addition, it is found that any combination of the efficiency and power supply is possible provided the link is driven over a critical frequency.
