Efficient Mid-range Wireless Power Transfer with Intelligent Surfaces (EMPTIS)

PI: Buon Kiong Lau (LU); co-PI: Alireza Saberkari (LiU)

Today, small devices can only be charged efficiently by wire connection or short-range, magnetic coupling based wireless power transfer (WPT), which is inconvenient to users. Long-range WPT has been attempted, but high efficiency will require impractically large antennas. EMPTIS, our proposed project, aims to leverage the widely-deployed large intelligent surfaces (LISs) envisioned for 6G to realize mid-range WPT with drastically improved efficiency, while ensuring safe operation for future green Internet-of-Things (IoT) devices and applications.
