The articles in this special section were presented at the 2014 IEEE Wireless Power Transfer Conference (WPTC)that was held in Jeju, Korea, May 8–9, 2014. Wireless power transfer technologies can provide us a freedom from hardwired connectivity when using electrical powers for mobile platforms, home appliances, and automotive vehicles. Furthermore, we can reduce the cost of system power wirings and will be able to reduce capacity and weight of batteries. Among the various wireless power transfer technologies, the resonant magnetic field technology can offer not only the highest power transfer efficiency, but also the higher wireless transmission power in near-field distance, especially for automotive wireless power charging applications.
