1. A magnetically-coupled wireless power transfer system, comprising:

  • a wireless power transmitter further comprising a plurality of transmitter magnetic field generating units;

    a wireless power receiver further comprising a plurality of receiver magnetic field generating units;

    an air gap separating the wireless power transmitter and wireless power receiver; and

    wherein said plurality of magnetic field generating units in the wireless power transmitter and wireless power receiver are arranged in an array such that the magnetic field strength is greater in the air gap between the wireless power transmitter and wireless power receiver than the magnetic field strength outside of the air gap separating the wireless power transmitter and wireless power receiver.
