Abstract :
Misalignments between high-Q resonators for mid-range wireless power transfer is analyzed. Implanting a simple filament coil based mutual inductance to the well known power transfer efficiency formula, theoretical predictions have been well agreed with measurement results. Some interesting phenomena regarding the misalignments have been found and analyzed.
