Abstract: Wireless power transfer refers to the use of electromagnetic waves to directly transmit energy from a source to loads without the need for cables or waveguide structures. As a new way of energy transfer and utilization, this technology can greatly improve the safety, reliability, and convenience of power devices, and may be applied in scenarios that require a high degree of freedom, such as consumer electronics, automated industrial workshops, and artificial intelligence platforms. Nevertheless, there are some limitations; in particular, magnetic resonance wireless power transfer, the technology of prime interest, still faces significant challenges in balancing efficiency and stability. Within the framework of near-field resonance wireless power transfer, this paper describes the control mechanism of non-Hermitian physics, as well as its outstanding advantages with regard to efficiency, stability, idle power loss, electromagnetic environment compatibility, and other aspects. Finally, the future research directions of wireless power transfer technology are summarized.
