摘要

摘要: 针对电磁波经孔缝耦合进入多端口微波混沌腔体的电磁辐射问题，推导了孔缝随机耦合模型，以预测单腔体各孔缝处耦合电压的统计特性；并将该模型与电磁拓扑理论结合，提出了一种复合计算方法孔缝随机拓扑模型，用于分析级联腔体的孔缝耦合电压和传输系数等电磁量的统计特性，将该算法的计算结果与网络级联理论的计算结果进行对比，验证了算法的正确性。该模型可成为分析复杂不规则混沌腔体的孔缝耦合问题以及混响室研究的有利工具。

Abstract: When the electromagnetic wave transports through apertures into the multi-port microwave chaotic cavities, random coupling mode for apertures is derived to predict the statistical characteristics of coupling voltage. A complex calculation method, aperture random topology model(ARTM), which combines random coupling model and electromagnetic topology theory, is proposed to determine the statistical characteristics of coupling voltage and transmission coefficient for interconnected cavities. This method is proved accurate through comparing results of ARTM and that of network cascaded theory. The results are beneficial for the analysis of the aperture coupling on complex irregular chaotic cavities as well as the research of reverberation chambers.
