Multipole Theory Analysis of the Higher Order Modal Characteristics of Circular-rectangular Coaxial Waveguide

由矩形外导体和圆柱内导体所组成的同轴波导在微波工程中具有重要价值 ,文中提出用多极理论分析圆矩同轴波导高阶模式 .实例计算结果表明 :多极理论是分析圆矩同轴波导的一种有效方法 ,不仅具有较高的计算精度 。

A new method, the multipole theory (MT) method, is presented for calculating the higher order modal characteristics of circular rectangular coaxial waveguides. The results obtained by the MT method are compared with the exact data reported in the literature. It is shown that the MT method is an accurate and reliable approach for analyzing the higher order modal characteristics of circular rectangular (C R) coaxial waveguide.
