摘要
为了能够将缩比模型应用于混响室设计中,对电磁场相似原理在混响室金属谐振腔体中的适用性问题进行了验证。分析计算了混响室缩比前后的模式数目,证明其符合相似原理;对构造的模型进行了仿真分析,表明缩比前后混响室金属腔体中观察点的电场值具有相似性;通过混响室实物的场均匀性测试数据验证了仿真分析方法的正确性。理论推导和仿真分析结果均说明电磁场相似原理可应用于混响室缩比模型中。
Validated applicability of electromagnetic similitude principium used in metallic resonance cavity for application of compact model in reverberation chamber design. Calculated mode number that is closely correlated with field uniformity character in reverberation chamber and its compact model, and results showed that mode number satisfied similitude principium. Illuminated field value of observed point in metallic cavity and its compact model have similitude character istic by simulation. Validated the correction of simulation method by the data of measurement. Results of deduction and simulation show that electromagnetic similitude principium can be used in compact model of reverberation chamber.
