We describe a wireless power transfer (WPT) system based on electromagnetic coupling of resonators in an array. The system can not only extend the effective range of a conventional resonant coupling based WPT system, but also provide power continuously to multiple moving devices, such as electric vehicles and robots. In this paper, the system is presented and analyzed with a transmission line model. The performance and characteristics of the system are studied and discussed.
