AI Technical Summary
Existing technologies cannot quickly and accurately test the equivalent conductivity of discontinuous conductive layers within large magnetic shielding devices, resulting in insufficient accuracy in high-shielding performance design and simulation.
A simulation-based inversion testing system and method are adopted. The conductivity, initial permeability and actual magnetic field strength of the magnetic shielding space of the magnetic permeable layer are obtained through the testing module. The data processing and simulation model inversion are performed by the processing module to determine the equivalent conductivity of the discontinuous conductive layer.
It enables accurate testing of the equivalent conductivity of discontinuous conductive layers within large magnetic shielding devices, improving the accuracy, convenience, and reliability of the tests, and providing core physical property data for the precise design of ultra-large zero-magnetic laboratories and magnetic brain/cardiac imaging shielding chambers.
