ABSTRACT This work proposes an eccentric conductor plate design aimed at overcoming the pervasive issue of diminished shielding effectiveness (SE) at the boundaries of traditional plates, thereby enabling wider and more efficient low‐frequency electromagnetic shielding. Compared to traditional flat and other shaped plates, the wave‐type configuration demonstrates superior SE and effective shielding area, compared to traditional plat type, achieving a maximum increase of 12.36% in SE at the point of maximum magnetic field intensity and 94.42% in effective shielding coverage. Utilizing 1600 finite element analysis (FEA) simulations, a Deep Belief Networks—backpropagation model was developed to capture multi‑parameter relationships. This led to the establishment of a multi‑objective geometric optimization procedure based on central SE, SE at the point of maximum field strength, and effective shielding area, thereby laying a foundation for practical engineering applications.
