Abstract:
The present invention provides a multi-load wireless power transfer system based on high-order Anti-PT symmetry. By introducing a “W-shaped” anti-resonance mode into a basic WPT platform, an effective Anti-PT non-Hermitian system is conveniently constructed. The “level attraction” of the anti-resonance mode is combined with the “level splitting” of the anti-resonance mode and the resonance mode, to study the “level pinning” effect of high-order Anti-PT symmetry. Compared with the traditional resonant WPT, the anti-resonant WPT has higher security, stability, transfer efficiency, and flexibility. Considering the miniaturization and integration of devices, a “meta coil” is designed by using a “synthetic dimension”, and used to construct a high-order Anti-PT symmetric system, thereby achieving multi-load efficient WPT. The new WPT technology based on the “level pinning” effect of high-order Anti-PT symmetry provides a good application research platform for enriching non-Hermitian physics.
