摘　　要：基于二维频域有限差分法(2-D FDFD),对梯形单脊矩形波导和梯形双脊矩形波导的传输特性进行了分析.采用直角坐标系中2-D FDFD的一般分析公式和波导梯形斜边上的差分公式,对梯形单脊矩形波导和梯形双脊矩形波导的传播特性进行了分析.数值计算结果和已有的数值结果以及仿真结果吻合得很好,证明了分析的正确性.Transmission characteristics of trapezoidal-ridge metal waveguide are analyzed using 2-D FDFD. The general 2-D FDFD equations in the Cartesian coordinate system and difference equations for the trapezoidal bevel edge of the waveguide are presented. Transmission characteristics of single and double trapezoidal-ridge waveguides are then analyzed using these equations. Computed results are in good agreement with the previously published ones, showing validity of the method.
