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.

Abstract: The present application provides a hydrophilic and hydrophobic composite packing-based rotating packed bed and a system. A hydrophobic packing and a hydrophilic packing are formed into a composite packing. When said packing cuts liquid, the hydrophobic packing can sufficiently disperse the liquid so as to make the dispersion of the liquid in the packing zone more uniform, and the wettability of the hydrophilic packing allows the liquid to spread sufficiently so as to increase the wetting efficiency of said packing. The phenomenon of droplet aggregation caused to liquid in a single hydrophobic packing zone and the phenomenon of reduction of liquid turbulence caused to liquid in a single hydrophilic packing zone can be avoided. Therefore, applying a hydrophilic and hydrophobic composite packing to a rotating packed bed can further improve the mass transfer and mixing performance thereof.
