摘要: 本文用高次有限元分析了任意横截面形状同轴线特性阻抗;给出了一个用二次元求解同轴线特性阻抗的通用程序。由于提出了一种便于编制通用程序的计算机自动区域剖分方法,使整个分析过程十分简便有效,大大提高了解题效率。文中对十余种不同横截面形状同轴线特性阻抗的计算,有力地证实了该程序的可靠性,通用性和准确性。同时,在数值分析的基础上,对高次元的解题效能进行了讨论。

Abstract: The high-order finite-element method is used for analyzing the characteristic impedances of the coaxial lines with arbitrary cross-sectons. A standard program with second order element analysis for calculating the characteristic impedances of various coaxial lines is developed. A computer automatic division technique is proposed to faciliate the development of the general program. As a result, the whole analysis procedure becomes simple and the solusion efficency raises tremendously. The calculations of the... -
