FEA simulations for low-frequency multi-layer magnetically shielded rooms

This paper proposes using Finite Element Analysis (FEA) simulations to optimize the design structure for low-frequency Magnetically Shielded Rooms (MSRs). In constructing a multi-layer MSR, different characteristics of material and laminated will bring levels magnetic Shielding Effectiveness (SE). The theoretical SE an MSR can be determined quickly. By method used in this paper, ideal found without increasing construction cost. According simulation results actual measurement we built, optimized improve by 13 dB. area where external field is 37 820 nT, as low 28 higher than 57.3 proposed research provide basis optimal FEA engineering practice, which effectively shielded rooms save obtained from following URL: https://github.com/YuukiAsuna/-Finite-element-simulation-of-material-lamination-sequence.
