摘要
为了对实际混响室的建造提供指导,采用基于矩量法的电磁仿真软件FEKO建立了混响室仿真模型,并通过实际测试对模型进行了验证。为高效地完成仿真,编写了Matlab程序控制FE-KO,实现了仿真模型中搅拌器的自动步进。从场强大小及电场标准偏差两方面对混响室模型进行了实验验证。结果表明:仿真计算得到的各顶点归一化最大电场强度趋势与实测结果具有较高的一致性,仿真计算得到的标准偏差值与实测结果的相对误差平均值保持在12%左右,说明仿真模型能真实反映混响室的场分布情况。
The modeling of reverberation chamber （RC） is realized using software FEKO based on mo- ment of method. The RC model working in the way of stepped tuner rotation is simulated. Matlab codes are programmed in order to make the stirrers step automatically, which improves the simulation effectively. The field uniformity testing software is exploited. The simulation model is verified from the aspects of field uniformity and normalized field strength. The results show that： the trend of normalized field strength at every vertex of working volume obtained from simulation is similar with experimental test, which shows the correctness of the RC model.
