1. A source device configured to control a magnetic field, the source device comprising:
- a plurality of source resonators configured to form the magnetic field to transmit power to one or more target devices;
a processor configured toverify a number of the one or more target devices and position of the one or more target devices, anddetermine a shape of the magnetic field in predetermined shapes of the magnetic field based on the number of the one or more target devices and the position of the one or more target devices to optimize transmission rates between the source device and the one or target devices; and
a phase changing unit configured to change a phase of at least one of the plurality of source resonators to form the magnetic field in the determined shape.
