High-Efficiency Wireless-Power-Transfer System Using Fully Rollable Tx/Rx Coils and Metasurface Screen
This work presents a high-efficiency reconfigurable wireless-power-transfer (WPT) system using fully rollable Tx/Rx coils and a metasurface (MS) screen working at 6.78 MHz, for the first time.The MS screens are placed between the Tx and Rx to magnify the power-transfer efficiency (PTE) of the WPT system.The proposed MS-based WPT can be rolled down
