摘要
Abstract
To achieve excellent electromagnetic shielding, the shielding effectiveness of a type chassis was simulated and analyzed using TLM solver provided by CST STUDIO SUITETM. By comparing the two kinds of excitation incidence modes, the common structures involving electromagnetic leakage were discussed, such as aperture arrays and seams. Further simulation analysis for the influence of screw spacing on the chassis shielding effectiveness was carried out. The simulation results show that excitation incidence modes have a significant impact on the shielding effectiveness of the apertures and seams. With the decrease of the screw spacing, the growth of its impact on the chassis shielding effectiveness declines. The research results provide a reference for electromagnetic shielding design and structure optimization of chassis.关键词
