The conventional inductive wireless power transfer (WPT) systems have a trade-off between transmission distance and size. Furthermore, when the transmitter and receiver go away from the line of axis, the performance due to this so-called misalignment will sharply drop. In this work, a new type of metasurfaces called stacked metasurface is proposed, and its effectiveness to mitigate above problems are studied experimentally. As a result, by using the proposed metasurface, we succeeded in achieving a transmission distance of 70 mm, which is more than double the maximum efficiency of 30mm transmission distance. As a result, we have raised their efficiency from 2% to 60%. |
