First claim
Opening claim text (preview).
What is claimed is: 1. A power transfer system comprising: a first coil coupled to a power source; a second coil coupled to a load; and a field-focusing element disposed between the first coil and the second coil and comprising a dielectric material and two open ends, wherein the field-focusing element is configured to develop a standing wave current distribution and focus a magnetic field onto the second coil, wherein the field-focusing element comprises multiple sets of resonators, each set of resonators configured to be excited to a different phase to facilitate focusing the magnetic field in a desired direction, and wherein the dielectric material comprises: an oxide compound comprising titanium; and a polymer material comprising a resin. 2. The power transfer system of claim 1 , wherein the field-focusing element comprises a plurality of resonators arranged in an array, and wherein the sets of resonators are configured to enhance the magnetic field in the direction of the second coil. 3. The power transfer system of claim 1 , wherein the field-focusing element comprises a single loop. 4. The power transfer system of claim 1 , wherein the field-focusing element comprises a spiral structure. 5. The power transfer system of claim 2 , wherein a resonator of the plurality of resonators is embedded in the dielectric material.
