随机耦合模型既继承了传统确定性电磁预测方法的优点，又能克服确定性预测方法对电大混沌腔体中电磁场量预测性能较差的问题。针对统计电磁学的研究运用现状，围绕混沌腔体的统计电磁预测技术，分析了随机耦合模型在理论研究及其测试应用中需要解决的非遍历性短周期耦合、任意孔缝辐射耦合及多腔体级联能量统计分析等关键技术及其研究思路，为随机耦合模型统计电磁预测技术的研究提供了一定的参考。

The random coupling model(RCM) not only inherits the advantage of traditional electromagnetic deterministic prediction methods, but also overcomes the problem that deterministic methods would cause a poor prediction of an electrical large chaotic cavity. Focusing on the state-of-the-art statistical electromagnetics and prediction in complex cavities, we studied the key technologies and notions of non-ergodic short ray coupling, random shape aperture coupling and statistical energy analysis in multi-cavity interconnection situation in both theory and testing, which provides references for research in RCM statistical electromagnetic testing.
