THE EFFECT OF A SMALL CONDUCTING FOREIGN BODYIN THE WAVEGUIDE
-
摘要: 本文利用矩形諧振腔中的教擾公式結(jié)合準(zhǔn)靜態(tài)近似,導(dǎo)出了矩形波導(dǎo)中小導(dǎo)體異物的等效串聯(lián)電抗和并聯(lián)電納。求出了反射系數(shù),傳輸相移及功率容量降低的表示式.這種表示式在試驗(yàn)中表明是適合的。

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. -
