Propagation Characteristics of Circular Coaxial Cables Filled with Multilayered Homogeneous Media and a Radial Conductor Plate

  • 摘要: 采用分离变量方法,推导了有径向导体板、填充均匀的多层各向同性介质的同轴线各层电磁场之间的递推关系,得到了第1层与第N层介质中电磁场的关系方程.利用电磁场的系数递推关系,进一步推出了此种同轴线的特征方程.将其用于只有1种各向同性介质填充情况,得到此种特殊情形下的特征方程.在内导体半径等于零的情形下,同轴线即变成具有径向导体板的圆波导,得到圆波导的特征方程.为展示其传播特性,给出了填充2层介质的同轴线及圆波导中一些模式传播特性的数值计算结果.
