| 摘 要： | 利用基于有限积分法的电磁场仿真软件CST仿真和分析了金属挡板对大型平行线栅有界波模拟器内部可用测试区和外部辐射电场分布的影响。首先建立了平行线栅有界波模拟器仿真模型，并依据GJB 8848证明了其合理性；而后重点分析了金属板对模拟器内部可用测试区电场分布的影响，并通过详实的数据列出了金属板位置、厚度、高度和长度等参数的具体作用效果；然后讨论了金属板对模拟器外部辐射电场的屏蔽效果；最后结合仿真结果提出金属挡板的设置应尽可能地远离模拟器，且有效反射面积越小越好，而对厚度无特别要求。

| Abstract: | The electromagnetic field simulation software CST based on the finite integral method was used to simulate and analyze the influence of the metal plate on the distribution of the available test volume and external radiated field in the large-scale parallel wire-grid bounded-wave simulator. First of all, the simulation model of the parallel wire-grid bounded-wave simulator was established, and its rationality was proved according to GJB 8848. Then the influence of the metal plate on the electric field distribution of the available test volume inside the simulator was analyzed in detail, and the effect of the location, thickness, height, and length of the metal plate were listed through detailed data. Moreover, the shielding effect of the metal plate on the external radiated electric field of the simulator was discussed. Finally, several suggestions for setting the metal protection plate were proposed. The conclusion is a good reference for effectively shielding the external radiation field without affecting the internal electric field distribution of the bounded-wave simulator. |
