Analysis of ridged elliptical waveguide by polynomial representation
脊加载椭圆波导的多项式表示分析方法

Application of ridged rectangular and circular waveguides has been found in many areas.In this paper,with the Rayleigh-Ritz method and polynomial representation,the wave propagation characteristics in the ridged elliptical waveguide are analyzed.The numerical results are in good agreement with calculation using electromagnetic field simulation software.The variation of bandwidth with physical dimensions has been studied.It is helpful for optimizing this kind of structure.
