Abstract: The laminated shielding performance of ferrite+ nanocrystalline (FN) is related to the material and structure. To solve the insufficient performance of traditional ferrite magnetic shield, a general laminated theory comprehensively considering material properties and structures was proposed, and the evaluation parameters and theoretical calculation formulas for magnetic shielding performance were given. Based on the proposed theory, the comprehensive performance of FN laminated magnetic shield was analyzed, and a novel FN laminated magnetic shield with excellent performance was designed. The finite element method was used to simulate and analyze the energy efficiency loss and space magnetic flux leakage of the laminated shield system. In order to quantitatively test the power loss, transmission efficiency and space magnetic induction intensity of the FN laminated shield system, the corresponding wireless power transfer experiment system and three-dimensional space magnetic field tester were built. Simulation and experimental results show that the proposed general laminated theory is feasible, and the novel FN laminated magnetic shield achieves an excellent performance which is superior to the traditional ferrite magnetic shield.
