过去,模匹配技术已被成功地用来分析具有横向不均匀性的矩形波导和圆波导。将此法推广用于分析圆锥波导的不连续性表明,它存在由于截止圆锥模式的特性而引起的难于收敛的问题。为了说明这个问题,本文将详细地讨论光壁圆柱波导与波纹圆锥喇叭的连接。 In the past, mode matching techniques have been successfully used to analyze rectangular and circular waveguides with lateral inhomogeneities. The generalization of this method for the analysis of the discontinuity of the conic waveguide shows that it has problems that are difficult to converge due to the characteristics of the truncated cone mode. To illustrate this issue, this article will discuss in detail the connection of a light-walled cylindrical waveguide to a corrugated cone horn.
