Wireless power transfer

The wireless power transfer technology started to attract extensive interest from the industry side in 2007 when the first smartphone was released and a consumer electronics revolution was triggered. Currently, the modern technology of wireless power transfer (WPT) already has a rich research and development history as well as outstanding advances in commercialization.

Our WPT research is devoted mainly to the studies of new physical phenomena and their applications for boosting the WPT performances.

In WPT systems conventional metallic coil resonators are used as key components for the field coupling. In our research, dielectric resonators, as a counterpart of metallic ones, have unique electromagnetic properties that enable more functionalities for WPT.

There are other practical application scenarios that power transfer to several receivers on a 2D platform, where we name it ‘smart table’. In our research, metasurface is used as a platform to implement the ‘smart table’. Different metasurfaces are designed to improve various functions, e.g. enlarged WPT distance, reduced electric field leakage.
