  "textContent": "A system (10) includes a first coil (14) mechanically coupled to a first component and electrically coupled to a power source (12). The system (10) further includes a second coil (16) mechanically coupled to a second component (18) and configured to receive power from the first coil (14) via a magnetic field. At least one of the first and second components includes a rotatable component. The system (10) also includes a field focusing element (22) disposed between the first coil (14) and the second coil (16) and configured as a self resonant coil having a standing wave current distribution to focus the magnetic field onto the second coil (16) and enhance the coupling between the first coil (14) and the second coil (16).",
