摘要：

This paper analyzes a low-frequency magnetic shielding effectiveness (SE) of a metal plate without and with a slot by using numerical simulation and analytic solution. When the metal without a slot has a low conductivity, the magnetic SE is determined by the diffusion effect which is the penetration of magnetic field through the metal plate due to a negligible reflection and small absorbtion. On the other hand, when the metal plate with a slot has a high conductivity, the magnetic SE is dominated by the slot penetration. The presented results in this paper can be used as guidelines in the shielding design and SE requirements of electromagnetic pulse protection facilities.
