【摘要】 空间电磁波对电子设备金属屏蔽腔体的电磁耦合是电子设备电磁兼容性的预测与分析的重要方面。建立了屏蔽腔体上孔阵的电磁耦合模型,介绍了孔阵电磁屏蔽效能的计算公式,并对高斯型脉冲激励下金属腔体上的方孔阵和不同间距的圆孔阵的电磁耦合能力做了数值仿真分析。数值分析结果对电子设备的电磁兼容性设计具有一定的工程实用价值,对最终实现电子设备的电磁兼容性有重要的指导意义。更多还原

【Abstract】 The electromagnetic coupling of electromagnetic wave to shielding cavity of electronic systems is an important factor of the electromagnetic compatibility prediction and analysis. The electromagnetic coupling model and formulations of shielding effectiveness for aperture arrays were proposed, and prediction and analysis for electromagnetic coupling of gaussian transient electromagnetic waves to square aperture arrays and circle aperture arrays of shielding cavity in electronic systems were done. The results play an important role to finally realize the electromagnetic compatibility of electronic systems.更多还原
