用伽辽金矩量法分析了同轴波导到圆波导的过渡。由于轴对称结构以及TEM模式入射波的假设，这是一个轴对称模式，从同轴和圆形波导中的不连续性的散射波可以表示为轴对称模式，因此，分析可以非常简化。反射特性计算作为频率的函数，并与参考文献中提出的结果非常吻合。该技术不仅适用于导电管道内壁减薄和裂纹的无损检测，而且适用于圆波导缝隙阵列天线的无损检测。
The coaxial-to-circular waveguide transition is analyzed using the Galerkin's method of moments. Because of the axisymmetric structure as well as the assumption of the TEM-mode incident wave, which is an axisymmetric mode, the scattered waves from the discontinuities in the coaxial and circular waveguides can be expressed as axisymmetric modes, and therefore, the analysis can be extremely simplified. The reflection characteristics are calculated as a function of frequency, and excellent agreement with the result presented in the reference literature is confirmed. This technique targets not only the nondestructive inspection of wall thinning and cracks inside conductive pipes but also the slot array antenna in circular waveguides.
