Abstract:
A resonator has an increased isolation for stable wireless power transmission. A material that reduces resonance coupling may be disposed in a space between each of a plurality of resonators and a resonator adjacent to each of the plurality of resonators. A material that reduces resonance coupling may be disposed on a plane opposite to a direction in which a resonator resonates. Power at an operating frequency set to be equal to or within a predetermined range of a frequency corresponding to a resonant mode may be injected into a plurality of transmission resonators.
