极化方向对含圆孔电磁屏蔽织物屏蔽效能的影响
Influence of Polarization Direction on the Shielding Effectiveness of Electromagnetic Shielding Fabric with Circular Hole
摘要
Abstract
The influence of polarization direction for electromagnetic wave on the shielding effectiveness of e-lectromagnetic shielding fabric with circular hole was studied.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 GHz.The test results show that circular hole has great effect on the shielding effectiveness of sample no matter vertical polarization wave or horizontal polarization wave.As the diameter increase of circular hole,the shielding effectiveness for both of them shows overall decrease trend.When the diameter of circular hold is larger than 10 cm,the shielding effec-tiveness of samples is close to zero.For the same frequency,there are obvious differences for the shielding effec-tiveness in directions of vertical polarization and horizontal polarization.It is considered that electromagnetic shiel-ding product can be designed based on the influence principle of circular hole on the shielding effectiveness of elec-tromagnetic shielding fabric.关键词
