摘要： 机载电子设备之间的间距很小,而且通常有用于散热的功能性孔阵,容易造成电磁泄漏,必须进行近场屏蔽效能分析.对比分析了采用有限元法的HFSS和传输线法计算孔阵近场屏蔽效能的结果,理论分析和计算结果均表明,传输线法不适合用于近场屏蔽效能计算.基于HFSS仿真分析,研究了相关参数对近场屏效的影响规律,提出了提高近场屏效的设计方法.

Abstract: The electromagnetic energy leakage through aperture arrays which were often designed for controlling temperature of avionics was inevitable. The near-field shielding effectiveness must be analyzed when the distance between two avionics was short. The calculation of near-field shielding effectiveness by the HFSS and the other one by the transmission line method was compared. Both the theory analysis and numerical results indicated that the transmission line method was noneffective in the calculation of near-field shielding effectiveness. The effects of some parameters on near-field shielding effectiveness were analyzed thoroughly by the HFSS. Some means for improving near-field shielding effectiveness was presented．
Key words: aperture array    shielding effectiveness    near-field
