摘要
应用法兰同轴测试装置测试了两组含有不同孔洞大小的电磁屏蔽织物的屏蔽效能,测试结果显示,不同大小的孔洞对屏蔽织物屏蔽效能的影响程度不同。当孔洞小于2 cm×2 cm时,织物的屏蔽效能几乎无差异;在孔洞大小为3 cm×3 cm时,织物的屏蔽效能明显下降;在孔洞大小为4 cm×4 cm时,其屏蔽效能几乎为零。因此,法兰同轴法测试含有孔洞的屏蔽织物的屏蔽效能有局限性。
The shielding effectiveness tests were implemented on two groups of shielding fabric with different pore sizes by using flange coaxial method. The different influence was shown from different pore sizes. When the pore size is less than 2 cm × 2 cm, the shielding effectiveness is almost no difference between the fabrics; in the pore size of 3 cm × 3 cm, its shielding effectiveness decreased significantly; in the pore size of 4 cm ×4 cm, its shielding effectiveness is almost zero. Therefore, the limitation by using flange coaxial method to test shielding fabric with holes was proved.
