Near-field focusing using MUSIC algorithm for wireless power transmission

A wireless power transfer system based on the concept of Near-Field Focusing is proposed. MUltiple Signal Classification (MUSIC) algorithm is used for localization and tracking, 2-D array of identical elements working at 2.4 GHz is used to focus the beam at the targets to be charged which are located in the near-field of the array. The proposed system ensures the delivery of a sufficient amount of power for driving the operation of implantable bio-sensors, RFIDs and mobile phones.
