Abstract

A power transmitter for wireless power transfer. The power transmitter includes (i) a material sheet encompassing a path based on a wireless power transfer area, and (ii) capacitors and inductive segments disposed along the path, mechanically supported by the material sheet, and connected in series into a string of distributed capacitors. Accordingly, the power transmitter is configured to transmit, from a RF power source and based at least in part on a characteristic frequency of the string of distributed capacitors, RF power across the wireless power transfer area via a near electromagnetic field of the string of distributed capacitors.
