摘要:

介绍了能够产生标准电磁场的横电磁波传播室(TEM小室)的基本结构及原理,着重研究了TEM小室的场均匀性.构建了一套采用TEM小室对电场探头校准的系统.为了评定校准结果的质量,本文还对TEM小室产生标准电场的影响因素进行了详细分析,进而对TEM小室产生标准电场的不确定度进行评定.

关键词: 电场探头; 校准; TEM小室; 标准电场; 不确定度

Abstract:

The basic structure and principle of TEM cell, which can generate standard electric and magnetic field,are introduced and field uniformity of the TEM cell emphatically studied. By using TEM cell, an electric field probe calibration system is established. In order to evaluate the level of calibration result, contributors of standard electric field generated by the TEM cell are analyzed in detail and the uncertainty of standard electric field evaluated.

Key words: electric field probe; calibration; TEM cell; standard electric field; uncertainty
