矩形波导中小导体异物的影响
THE EFFECT OF A SMALL CONDUCTING FOREIGN BODYIN THE WAVEGUIDE
-
摘要: 本文利用矩形谐振腔中的教扰公式结合准静态近似,导出了矩形波导中小导体异物的等效串联电抗和并联电纳。求出了反射系数,传输相移及功率容量降低的表示式.这种表示式在试验中表明是适合的。Abstract: The equivalent series reactance and parallel susceptance of a small conclucring foreign body in the rectangular waveguides are derived by using perturbational formula in the rectangular cavity and combining with quasi-static approximation. The expressions of its reflection coefficient, transmission phase displacement and power carrying capacity reduction are also given. The expressions are shown that is satisfactory in experiment.
