摘要
介绍了电磁屏蔽服的屏蔽机理以及屏蔽效能测试的基本原理。针对现有屏蔽室内屏蔽效能测试法成本高的缺点,在分析服装屏蔽电磁波原理的基础上,分析了一种基于着装人体的屏蔽服屏蔽效能测试方法--GTEM小室法,分析了其测试的原理、测试方案的设定以及适用范围,指出GTEM室造价低,所用仪器配置简单,频域比较宽,能够满足高频电磁辐射环境的测量,但也存在场均匀性有限的问题。
In this paper, the shielding mechanism of electromagnetic shielding clothing and the fundamental principle of shielding effectiveness testing are introduced. In view of the principle of clothing shielding electromag- netic wave and in order to reduce high cost for testing shielding effectiveness in shielded room, one testing method--GTEM cabinet method is presented. This shielding effectiveness testing method is based on dressed body, ils testing principle, setting of testing scheme and scope of application are analyzed. The results show that the cost of GTEM cabinet is less, the needed instrument is simple, the frequency domain is wider, which is suitable tot lcsting the high frequency electromagnetic wave. However, the uniformity of its magnetic field is limited.
