| 摘 要： | 为研究屏蔽布结构和屏蔽效能的关系,进而为电磁屏蔽帐篷的设计提供依据,建立了屏蔽布的简化等效物理模型,采用时域有限差分(FDTD)方法分析计算了单层、双层屏蔽布的屏蔽效能.比较了单层、双层屏蔽布的屏蔽效能的数值计算结果和实测结果,二者吻合较好.计算分析表明,在15 MHz～10 GHz范围内,双层屏蔽布的屏蔽效能明显高于单层屏蔽效能,电磁波斜入射时双层屏蔽布的屏蔽效能略高于垂直入射的屏蔽效能,双层屏蔽布存在灾难性谐振现象.并提出了消除灾难性谐振的具体措施.

| Abstract: | To research the relation between the structure of the shielding fabric and the shielding effectiveness for the design of electromagnetic shielding tent,the simplified equivalent model of the shielding fabric was established.The shielding effectiveness of the single-layer and double-layer shielding fabric was cal culated with FDTD method.There was a good agreement between the numerical results and the experimental results.The numerical results show that the shielding effectiveness of the doublelayer shieldin... |
