    Nonidentical current control methods for 2- and 3-D
    omnidirectional wireless power systems are described. The omnidirectional power transmitter enables ac magnetic flux to flow in all
    directions and coil receivers to pick up energy in any position in the
    proximity of the transmitter. It can be applied to wireless charging
    systems for low-power devices such as radio-frequency identification devices and sensors. Practical results on 2-D and 3-D systems
    have confirmed the omnidirectional power transfer capability
