任意形状的H面矩形波导不连续性的有限元分析

FINITE-ELEMENT ANALYSIS OF H-PLANE DISCONTINUITIES OF ARBITRARY SHAPE IN A RECTANGULAR WAVEGUIDE

应用伽辽金有限元法研究了任意形状的 H 面矩形波导不连续性问题,场域剖分采用了二阶三角形单元.编制了一个通用的计算机程序,对 x 波段矩形波导 H 面弯曲和 T 型结头进行了计算,结果与文献吻合.

In the paper.the Gelerkin finite-element method is used for the analysis of H-plane discontinuities of arbitrary shape in a rectangular waveguide.In order to ensure accu- racy of solution.The field region is divided into a number of 2nd-order triangular element.A computer program is drawed up for calculating the H-plane corner bend,H-plane T-junc- tion of x wave band.The results in the paper agree well with the reference.
