Abstract

A source resonator for wirelessly transmitting power to a target device may include a magnetic field distribution adjusting unit that is configured to adjust the magnetic field generated by the source resonator. In one or more embodiments, the magnetic field distribution adjusting unit may adjust the magnetic field to be substantially uniform in a predetermined vicinity of the source resonator. For example, the magnetic field distribution adjusting unit may adjust the intensity of the magnetic field near the center of the source resonator to be substantially the same as the intensity of the magnetic field near an edge area of the source resonator.
