摘要
提出了一种测试任意复杂截面波导截止波长的新方法。该方法利用波导及谐振腔的有关理论，把任意复杂截面波导的截止频率测试问题转化为对波导谐振腔的测试，因而不但在测试中回避了匹配和过渡等难题，而且达到较高精度，非常适合于微波工程设计使用。还提出了对波导衰减以及模式场分布的测试方法。
A novel method for measuring the cut off wavelength of waveguides with arbitrary complex cross sections is proposed in this paper. Based on the theory of waveguide resonant cavity, the measurement of complex waveguides is simplified into that of resonant cavities. Consequently, the difficulties of matching and transition are excluded, and high accuracy is also obtained. This measurement method is regarded as a better choice in microwave engineering design. The measurement methods for waveguide attenuation and field distribution are also included.
