Summary :
In this letter, we propose a novel wireless power transfer (WPT) scheme in the radiative near-field (Fresnel) region, which based on machine vision and dynamically reconfigurable holographic metasurface aperture capable of focusing power to multiple spots simultaneously without any information feedback. The states of metamaterial elements, formed by tunable meander line resonators, is determined using holographic design principles, in which the interference pattern of reference mode and the desired radiated field pattern leads to the required phase distribution over the surface of the aperture. The three-dimensional position information of mobile point sources is determined by machine visual localization, which can be used to obtain the aperture field. In contrast to the existing research studies, the proposed scheme is not only designed to achieve free multi-focuses, but also with machine vision, low-dimensionality, high transmission efficiency, real-time continuous reconfigurability and so on. The accuracy of the analysis is confirmed using numerical simulation.
