摘要
介绍了Cassinian和SN波导的基本理论,分别给出了用于描述这两种波导的曲线方程,通过求解这两种波导的曲线方程并利用HFSS三维场仿真软件设计了工作在X频段的两种特殊形状的波导,实际测试了这两种波导的色散特性、衰减常数、传输功率容量和波阻抗,并对测试结果进行了详细的分析与讨论,初步论证了Cassinian和SN波导用于大功率微波能量传输的可能性,为这两种波导的实际应用打下了良好的基础。
The basic theory of Cassinian and SN waveguides is presented in this paper, based on the former researches. The curve equations used for describing these two types of waveguides are proposed respectively. Through solving these curve equations, waveguides working in X band are designed using HFSS software. The frequency dispersion, attenuation, power handling and wave impedance of these two types of waveguides are measured, and the measurement results are analyzed and discussed in detail. The foundation of application of high power microwave transmission for the waveguides are built up.
