Abstract:
This paper introduces the mechanism of radiation disturbance and the principles of magnetic ring restraining radiation disturbance,establishes the model of magnetic ring restraining radiation disturbance,deduces the theoretical expression of magnetic ring restraining electromagnetic interference by using Biot-Savart law,and analyzes and simulates the influence of magnetic ring shape and magnetic permeability on restraining effect by MATLAB. The results show that the electromagnetic interference suppression effects changes faster with the magnetic ring length than with the outer diameter,and the change trend of the suppression effect is positively correlated with the magnetic permeability. The influences of magnetic ring shape and magnetic permeability on the suppression effect are experimentally analyzed by using 3m anechoic chamber. The simulation results are consistent with the experimental results.
