摘　　要：基于积分方程法的分析途径，本文提出计算任意截面柱形金属波导中主模和高次模的特征值和特征向量的数值方法。本文运用此方法对非对称单脊波导进行了深入的理论和实验研究，给出了该种波导的本征值、电中心线偏移量、壁电流分布、带宽特性、损耗和功率容量等的理论计算结果，这些结果对非对称单脊彼导共线裂缝阵天线单元设计有较高的实用价值。Based on the analytical procdures of the integral equation, a numerical method for thecalculation of the eigen-value and eigen-vector of all the modes (the main-mode and high-order modes) ofthe cylindrical waveguide with arbitrary cross-section is presented. The results of theoretical andexperimental study on asymmetric ridge wampide, such as eigen-value, electrical centerlinedighacement, wall-current distribution, handwidth, loss and powr capacity, are given. Thase results arevery helpful to the design of asymmetric ridge waveguide slotted array antenn elements where radiatingslots located on a common geometrical centerline.
