Wireless power transfer is increasingly and more widely used in recent years. As wireless communications has changed and dominated our lives and business dramatically, wireless power is expected to make people get free from wires and fear of battery discharge. Different from the wireless communications, however, wireless power needs much more innovations and efforts to open the ubiquitous wireless power era. To promote the development of wireless power technologies, the workshop on wireless power sponsored by IEEE will be held in Seoul, Korea as a part of VTC conference. It is recommended for advanced engineers to present their papers at this workshop, where a few plenary speakers present their recent achievements.
