| 摘 要： | 本文用光学法与广义散射矩阵技术相结合的方法,根据波导在入射平面电磁波照射下所激励的波导模式,分析了终端短路金属圆波导的电磁散射特性。在此基础上,假设金属波导内壁涂层厚度τ远小于波导半径a,且波导入口段的涂层厚度从零线性增加至τ,运用微扰法求出终端短路涂层金属圆波导内各波导模的传播常数,从而获得涂层圆波导的电磁散射特性。通过计算机仿真,计算了终端短路涂层金属圆波导的雷达截面(RCS),并与相同条件下内壁无涂层金属圆波导的雷达截面进行比较,结果令人满意。

| Abstract: | This paper analyzes the transmitting properties and electromagnetic scattering properties of a coated circular waveguide terminated by a perfect electric conductor (PEC),using the perturbation method based on the analysis of electromagnetic scattering properties of a metallic circular waveguide terminated by a PEC. Computer simulation is made. The radar cross-section (RCS) of a coated circular waveguide terminated by a PEC is calculated and compared with the RCS of a metallic circular waveguide with closed termination. The results obtained are satisfactory. |
