采用有限元法研究了圆形和椭圆形两种变形对称双脊波导对传输特性的影响。计算了脊的尺寸变化时的截止波长和单模 带宽，给出了主模场结构 图以及变形对截止 波长和单模带宽影响的关 系曲线 ，并分析 了传输特性 随对称脊波导结构尺寸变化的情况。通过这些研究，能够为变形双脊波导的应用和研究提供有价值的参考。 (Finite element method using the circular and elliptical symmetry Double Ridge Waveguide two deformation characteristics of the transmission. Dimensional changes were calculated when the ridge and single-mode cutoff wavelength bandwidth gives the dominant mode field pattern and deformation of single-mode cutoff wavelength and the bandwidth of the curve, and analyzed the transmission characteristics of ridge waveguide structure with symmetrical changes in size situation. These studies can be applied for the deformation Double Ridge Waveguide to provide a valuable reference and research.)
