在本文中，我们提出了一种通过应用基于平面电路方法的H平面波导不连续性分析技术来分析后壁波导（PWW）或衬底集成波导（SIW）的方法。分析过程包括规则形状电路的模式阻抗矩阵的推导以及对布置在金属柱外围的虚拟端口的短路操作。首先以PWW直线段为例，详细介绍S参数计算的解析方法。然后借助直通反射线 (TRL) 校准技术计算 PWW 的衰减和相位常数。接下来，将解析方法应用于两种直角角的设计。使用仿真器（HFSS）验证了分析和设计结果。
In this paper, we suggest a method of analyzing the post-wall waveguide (PWW) or the substrate integrated waveguide (SIW) by applying the analytical technique of the H-plane waveguide discontinuities based on the planar circuit approach. The analytical procedure consists of the derivation of the mode impedance matrices for regular-shaped circuits and the short-circuiting operation on fictitious ports arranged at the peripheries of the metallic posts. First, a straight section of the PWW is treated as an example and the analytical method for the calculation of the S-parameters is described in detail. Then the attenuation and phase constants of the PWW are computed with the aid of the Thru-Reflect Line (TRL) calibration technique. Next, the analytical method is applied to the design of two types of right-angled corners. The analysis and the design results are verified using an em-simulator (HFSS).
