Abstract
We demonstrate by theoretical analysis and experimental
verification that mid-range wireless energy transfer systems may take advantage of de-tuned coupling devices, without jeopardizing the energy transfer efficiency. Allowing for a modest de-tuning of the source coil, energy transfer systems could be properly designed to minimize undesired energy dissipation in the source coil when the
power receiver is out of the range. Our basic observation paves the way for more flexible design and fabrication of non-resonant mid-range wireless energy transfer systems, thus potentially impacting practical implementations of wireless energy transfer.
