摘　　要：研究电磁波极化方向对含圆孔电磁屏蔽织物屏蔽效能的影响。选择不锈钢电磁屏蔽织物制作含圆孔的样布,在1GHz^18GHz范围内分别测试垂直极化与水平极化方向样布的屏蔽效能。结果表明:无论是垂直极化波还是水平极化波,圆孔对样布屏蔽效能的影响均较大;随圆孔直径增大,屏蔽效能均呈整体降低趋势;圆孔直径大于10cm时,样布屏蔽效能接近零。相同频率下,样布在垂直极化方向和水平极化方向的屏蔽效能差异明显。认为:根据圆孔对电磁屏蔽织物屏蔽效能的影响规律可以设计相关电磁屏蔽产品。The influence of polarization direction for electromagnetic wave on the shielding effectiveness of electromagnetic shielding fabric with circular hole was sludied. Stainless steel electromagnetic shielding fabric was selected for the preparation of samples with circular hole. The sample shielding effectiveness in the direction of vertical polarization and horizontal polarization was tested among the range of 1 GHz~ 18 （]-Hz. The test results show that circular hole has great effect on the shielding effectiveness of sample no mailer vertical polarization wave or horizontal polarization wave. As the diameter increase of circular hole, the shielding effectiveness for both of lhem shows overall decrease trend. When the diameter of circular hold is larger than 10 em,the shielding effec tiveness of samples is close to zero. For the same frequency,there are obvious differences for the shielding cffec tiveness in directions of vertical polarization and horizontal polarization, h is considered that electromagnetic shiel ding product can he designed based on the influence principle of circular hole on the shielding effectiveness of elec- tromagnetic shielding fabric.
