摘要
矩形波导中感性膜片的传统分析都局限于理想金属膜片的情况,不能反映其导体损耗特性。本文应用直线法分析非理想导体所构成的薄感性膜片,其等效电抗和等效电阻能同时计算获得。文中给出了几种典型感性膜片等效阻抗的数值结果。作为一应用实例,分析了有耗双膜片通过式谐振腔的传输特性。
Traditional analyses for inductive diaphragms and strips in rectangular waveguides have been restricted to the case of perfectly conducting metal sheets. In this paper, the diaphragms and strips with finite conductivity are studied by the method of lines. The equivalent resistances as well as the equivalent reactances of the discontinuities can be calculated simultaneously. As an example of their applications,a lossy resonant cavity consructed with two symmetrical diaphragms is analysed.
