中文摘要

混响室作为一种新兴的电磁兼容测试设备具有重要的应用价值。混响室的概率统计模型是描述混响室内的场环境的有效方式。本文总结了混响室的概率统计模型,应用蒙特卡洛方法模拟了基于模式理论的混响室模型,对混响室内的场线耦合问题进行了深入的研究。获得了混响室中单导体传输线终端负载响应的数值解,与已有的结果对比较为吻合,并通过对传输线与腔壁距离变化的研究,讨论了混响室内的场均匀性,这也意味着基于模式理论的概率统计模型能够更精细地描述混响室电磁环境。

英文摘要

As a new kind of equipment for electromagnetic compatibility (EMC) testing, reverberation chambers (RCs) have important application value. Probabilistic and statistical model of RCs can be used to describe the EM field environment of RCs. In this paper, some probabilistic and statistical models of RCs are summarized. The model based on mode theory is adopted and a Monte Carlo (MC) method is applied to simulate the EM field environment in a RC numerically. And then the problem of field-to-wire coupling in the RC is considered. Terminated load response of a single wire in the RC is analyzed. The obtained results are consistent with the results obtained by existing solutions. By changing the distances of wire and walls, the field uniformity in the RC is discussed, which implies that the mode-theory-based model can describe the EM environment in RCs in more details.
