摘　　要：将矢量有限元方法应用到脊位于窄边的四种加载介质双脊波导的场结构特性计算中,这其中包括脊位于窄边的加载介质双脊矩形波导、脊位于窄边的加载介质双脊V形波导、脊位于窄边的加载介质双脊椭圆形波导以及脊位于窄边的加载介质双脊梯形波导。多种模式的场结构特性随脊尺寸的变化而变化,其图形结果将有助于微波器件的设计。The edge-based vector finite element method is introduced to calculate the field patterns in four types of dielectric-loaded double-ridge waveguides of the ridge on theshort side, including double-rectangle- ridge waveguide, double-V-ridge waveguide, double-elliptical-ridge waveguideand double-trapezoidal-ridge waveguide. The changes of the field patterns of various modes by changing ridge dimensions are analyzed. The figures are considered to be helpful in the design of many microwave components.
