| 摘 要： | 该文计算了在矩形腔上开有单缝时，缝长变化对所激励的屏蔽腔中最低模式的幅度和频率特性的影响。同时，采用时域-频域联合分析的方法，对屏蔽腔内观察点时域波形进行了分析，得到了不同频率分量在时域上的变化特性，以及缝长变化对它们的影响。

| Abstract: | The shielding effectiveness of a rectangular enclosure perforated with a slot is analyzed and the influences of the slot length on the magnitude and frequency of the lowest mode stimulated by the slot are given. Joint time-frequency analysis is also applied to explore the time domain waveform of every frequency component at observation point. The influence of the slot length to the time domain characteristics of different resonant mode is also obtained. |
