Power is transferred wirelessly through a 3.1-mm thick aluminum barrier without any physical penetration and contact. Measurement results show that the class-E PA achieves a peak power gain of 25.2 dB and a maximum collector efficiency of 57.3%, all at 200 Hz. The proposed system obtains a maximum power transfer efficiency of 9% and it can deliver 5 W power to the receiver side through the aluminum barrier. publisher: Institute of Advanced Engineering and Science date: 2019-12 type: Article type: NonPeerReviewed format: application/pdf language: en identifier: https://eprints.uet.vnu.edu.vn/eprints/id/eprint/3464/1/Power_amplifier.pdf identifier: Vu, Tuan Anh and Pham, Van Chi and Pham, Anh Vu and Gardner, Christopher (2019) Wireless Power Transfer Through Metal Using Inductive Link.
