Wireless Power Transfer Based on Microwaves and Time Reversal for Indoor Environments [PDF]

IEEE Access, 2019
Resorting to power accurate delivery for wireless power transfer (WPT) based on microwaves, a theory and method based on time reversal (TR) for WPT in 3D indoor environments are presented in this paper. Conventional WPT methods have the limitations of requiring that the elements on power source array (PSA) must have the same structure and regular ...
