摘要: 本文從廣義電報(bào)方程出發(fā),在確定的邊界條件和連續(xù)性條件下,得到了緩變截面波導(dǎo)腔中振蕩模的諧振頻率、品質(zhì)因數(shù)和場分布的公式。著重研究了開放式緩變圓截面波導(dǎo)腔中HORP模振蕩,特別是這些模在開口處的衍射損耗;最后對(duì)常用的一種雙圓錐開放腔體進(jìn)行了分析,得到了一組較為通用的諸振頻率和品質(zhì)因數(shù)的曲線。已有的實(shí)驗(yàn)證實(shí)了曲線的可靠性。

Abstract: In this paper, from the generalized telegraph equations waveguide cavities with slowly varying cross-section are studied. The mode resonant frequencies and the quality factors (Q s) of these cavities and the field distributions are found when the boundary conditions at the ends and at discontinuities are given. Honp modes in an opend circu-lar waveguide cavity with slowly varying cross-section are studied in some details, espe-cially the diffractive losses of these modes at the opened ends of the cavity are obtained. Finally, two sets of universal curves for resonant frequencies and Q's are given fro the double conic opened cavities which are most frequently used in practice. Some results of experiments prove their use rather reliable. -
