摘要

本文提出了一种新的等效圆波导半径表达式，改进了计算圆锥波导内电磁场的传播常数，波阻抗和场分量的计算精度，运用数值对比方法，证明新的表达式在高次模和近截止区仍有较好的适用性．最后结合实例讨论了相关的插值方法，以便处理工程设计中常见的特征值非整数时的计算问题．

Abstract

A new equvialent expression of the electromagnetic field in a conical waveguide is presented

by which the deviations of the calculated propagation constant and wave impedance from the exact values

the field components from the asympotic solution

are improved.It is especially of advantage for the prediction of the phase shift and the field charicteristics in the region of near cutoff of higher order modes

by which the problem of unintegral eigenvalues confronted in engineening design can be solved.
