This study presents the electromagnetic (EM) field uniformity analysis of the Korean National Radio Research Agency (RRA) reverberation chamber (RC). The analysis is performed using the normative procedure of International Electrotechnical Commission (IEC) 61000‐4‐21 for the estimation of the lowest usable frequency (LUF) of the RRA RC based on the field uniformity characterization. A full‐wave EM model of the RRA RC is designed using the method‐of‐moments (MOM) technique. The triaxial electric fields at the eight corners of the defined working volume are measured using electric field probes for the complete revolution of the mechanical stirrer. The experimental data are obtained for the frequency range of 80–1,000 MHz through the designed data acquisition software. The post‐processing of the experimental and simulation data in terms of calculation of standard deviation of recorded E‐field data, and its comparison with the defined standard deviation limit in IEC 61000‐4‐21 standard is performed to obtain the LUF of the RRA RC. A good degree of agreement was observed between the simulated and measured results of the RC field uniformity.

无线电研究局混响室的设计,分析和验证
这项研究提出了韩国国家无线电研究局(RRA)混响室(RC)的电磁(EM)场均匀性分析。使用国际电工委员会(IEC)61000-4-21的规范性程序进行分析,以基于场均匀性特征估计RRA RC的最低可用频率(LUF)。使用矩量法(MOM)技术设计了RRA RC的全波EM模型。使用电场探头测量所定义工作体积的八个角处的三轴电场,以使机械搅拌器完全旋转。通过设计的数据采集软件可获得80–1,000 MHz频率范围内的实验数据。根据记录的电场数据的标准偏差的计算,对实验和模拟数据进行后处理,并将其与IEC 61000-4-21标准中定义的标准偏差极限进行比较,以获得RRA的LUF RC。在RC场均匀性的模拟和测量结果之间观察到了很好的一致性。
