開縫矩形腔屏蔽特性的研究
Analysis on Shielding Effectiveness of Rectangular Cavity Perforated with a Single Slot
-
摘要: 該文計算了在矩形腔上開有單縫時，縫長變化對所激勵的屏蔽腔中最低模式的幅度和頻率特性的影響。同時，采用時域-頻域聯(lián)合分析的方法，對屏蔽腔內(nèi)觀察點時域波形進行了分析，得到了不同頻率分量在時域上的變化特性，以及縫長變化對它們的影響。

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. -
