Latest Patents

Kejia Zhu holds a patent for a "Multi-load wireless power transfer system based on high-order anti-PT symmetry." This invention introduces a 'W-shaped' anti-resonance mode into a basic WPT platform. By constructing an effective Anti-PT non-Hermitian system, the invention combines the “level attraction” of the anti-resonance mode with the “level splitting” of both the anti-resonance and resonance modes. This research explores the “level pinning” effect of high-order Anti-PT symmetry. Compared to traditional resonant WPT systems, this anti-resonant approach offers enhanced security, stability, transfer efficiency, and flexibility. The design of a “meta coil” utilizing a “synthetic dimension” further supports the miniaturization and integration of devices, achieving efficient multi-load WPT.
