ANALYSIS OF SOME PROPAGATION PROPERTIES OF INSULAR DIELECTRIC WAVEGUIDE

摘要: 本文研究了绝缘介质波导两类模式的本征方程的不同表达形式对基模Ey11截止特性的影响,指出采用三角函数的表达形式可避免导致Ey11模有非零截止这一不恰当的结论,推导了四个低阶模存在的条件。在此基础上用正交选优法对绝缘介质波导影响传输特性的五个参数进行选优,得到多组单模带宽较宽,导体损耗和介质损耗较小、外场发散也较小的参数,并与镜象波导作了对比。

Abstract: The conditions for four lower modes existing in an insular dielectric waveguide are given. The parameters which affect the propagation properties Of the insular dielectric waveguide are selected optimally by the improved Orthogonal Array Table (OAT). Then a set of parameters for obtaining wider single mode bandwidth, lower conductor and dielectric loss, and small outer field dispersion is given. The single mode bandwidth of insular dielectric waveguide is compared with that of image waveguide, and the difference is not significant. -
