摘要：
This paper describes a numerical method for analysis of electromagnetic fields around thin ferromagnetic layers with time-dependent source currents. In this method, the electromagnetic fields inside the thin layer are assumed to obey the one dimensional magnetic-diffusion equation while the field in air around the layer is assumed to be a quasi-static magnetic field in full dimensions. The nonlinearity in the magnetic characteristics of the ferromagnetic material is taken into account. The interior and exterior fields are analyzed by finite and boundary element methods, respectively. The present method gives results similar to experimental results for a shielding thin plate.
