摘要
用已提出的新的分析任意截面槽波导的傅立叶展开-差分法对填充非均匀介质的矩形波导进行了分析,验证了其正确性,并对一种填充具有周期分布介质的矩形波导的截止特性和色散特性进行了数值计算和分析。该方法可以便捷地解决波导在微波毫米波应用中的实际工程问题,对研究其它非均匀波导问题有一定的参考价值。
The rectangular waveguide filled with non-symmetrical dielectric is analyzed by using a new Fourier＇s expansion-differential method for analyzing groove guide with arbitrary shape, and the correctness of the new method is verified. In addition, a new type of waveguide filled with periodic homogeneous dielectric waveguide is analyzed. The new method has the advantages of simple and easily feasible computation to solve the engineering problem in microwave and millimeter wave＇s application. So it is of available for analysis of other waveguides filled with non-homogeneous dielectric.
