Abstract
The metasurface-based concept of a smart table for wireless power transfer (WPT) has been recently proposed and experimentally proven to be capable of transferring energy to 1 m with high efficiency. However, in reality, we usually encounter the need to transfer energy to several receivers and with the presence of various obstacles. Herein, we explore the capabilities of the smart table scenario in charging multiple receivers simultaneously. It is demonstrated numerically that the total WPT efficiency as high as 90% to both receivers can be obtained in a wide range of the operational distance. Also, we study the system performance in presence of different types of obstructions in vicinity of the smart table. We demonstrate that in many practical cases dielectric and metallic obstructions do not reduce the WPT efficiency much owing to the surface mode localization and symmetry. Our findings make the metasurface-based smart table system one step closer to the real-life applications.
