Abstract

In this paper, finite element method is used to study the strong electromagnetic pulse into the computer box with holes to calculate the influence of shielding the computer box. Then strong electromagnetic pulse coupled into the shielding box with holes is studied in the same way. The relationship between the simulation resonance frequency and the theoretical results are calculated by research different the computer boxes’ shielding effect under different electromagnetic pulse’ frequency; the influence of the holes’ shape and size on shielding effect is also simulated. It is concluded that the computer box’s shielding effect is poor under the resonance frequency, and there are no linear relationship between shielding effect and hole’s size. The shielding effect becomes worse because of resonance coupling with the size of the hole unchanged the holes’ size.
