HIGH-ORDER FINITE ELEMENT ANALYSIS OF DISPERSION AND LOSS CHARACTERISTICS OF GROOVE GUIDE WITH ARBITRARY SHAPES
-
摘要: 本文用高次有限元法分析了任意形狀槽波導的色散和損耗特性.該方法的有效性和可靠性由實驗和其它計算結果所證實.文中對諸如矩形、三角形、拋物、橢圓和余弦等形狀的槽波導進行了系統(tǒng)的研究.計算結果表明,不同形狀槽波導具有相近的色散特性,但損耗相差很大,其中V形槽波導損耗最小,大約是矩形槽波導的一半.文中給出的曲線可供設計槽波導元件和電路時參考.

Abstract: The dispersion and loss characteristics of groove guide with arbitrary shapes are analyzed with high-order finite element method. The effectiveness and the reliability of the method are verified by the experiments and the results obtained by other mehods. Groove guides with various groove shapes, such as reorangular, triangular, parabolic, elliptic and cosine functions are investigated systematically. The calculating results show that the dispersion of groove guide with different groove shape is almost the same; the loss characteristic is rather different, among them. V-shape groove has the lowest loss, which is about half of the loss of rectangular groove guide. All the curves and .the data given in this paper can be used in designing the elements and circuits composed of the groove guide. -
