Research on Radio Energy Transmission System Based on Parity-Time Symmetry

Magnetically coupled resonant WPT technology can realize long-distance power transmission, which is currently a research hotspot. However, in practical applications, the position between the receiving and transmitting coils is not fixed, and its transmission power and efficiency are greatly affected by the coupling coefficient, which hinders the application and promotion of magnetic coupling resonance technology. To solve this problem, this paper proposes a magnetically coupled resonant radio energy transmission system based on parity time symmetry, designs the system structure, analyzes and explains its working principle and characteristics in detail, and finally verifies the practicability and rationality of the system through simulation analysis.
