| 摘 要： | 使用解析方法研究了缝隙偏离中心的有孔屏蔽腔屏蔽效能。将有孔腔体的屏蔽和传输特性用等效传输线的高次模进行分析,推导了平面波以任意角度和极化方向入射时,有孔腔体屏蔽效能的解析计算表达式。分析了入射角度、极化方向、孔缝尺寸、测试点位置、腔体壁损耗、工作频率等参量与腔体屏蔽效能的关系。经与腔体谐振频率比对,表明该解析方法得到的结果可信,而且解析公式计算速度快,利于参量分析,能为屏蔽腔体设计提供依据。

| Abstract: | Shielding effectiveness of enclosure with off-center aperture is investigated by using analytical method.Through modeling the shielding and propagation characteristic of enclosure with high order mode equivalent transmission line,the shielding effectiveness of enclosure with aperture is formulated when plane wave is incident with arbitrary incident angle and polarization direction.Relationship between shielding effectiveness and incident angle,polarization direction,aperture size,loss of enclosure wall,test... |
