This workshop provides a forum for researchers and developers working on Wireless Power Transfer (WPT) to facilitate and highlight developing WPT technologies, to determine and advance the state of the art, to discuss supporting and related technical issues in this area, and take necessary action to improve implementations.

It investigates WPT applications in Space-to-Ground (Space Solar Power), Space-to-Space, Ground-to-Space and Ground-to-Ground power transfer. Study of multi-layer power transfer (e.g., air-to-water, air-to-body), policies, and economics of WPT will also be considered.
