本文提出了一种数值模拟随机电磁场近场和远场传播的有效方法。该方法是基于使用绿色函数或场传递函数计算确定性字段的场相关并矢的变换。该方法考虑了噪声辐射源之间的任意相关性，并允许计算噪声电磁源的谱能量密度的空间分布。所介绍的方法可以与现有的电磁建模工具相结合。结果表明，矩量法可以应用于解决噪声电磁场问题的网络方法，应用相关矩阵技术。的辐射噪声场的空间分布的源之间的相关性的强烈影响的例子。
In this paper, an efficient method for the numerical simulation of near- and far-field propagation of stochastic electromagnetic (EM) fields is presented. The method is based on the transformation of field correlation dyadics using Green's functions or the field transfer functions computed for deterministic fields. The method accounts for arbitrary correlations between the noise radiation sources and allows to compute the spatial distribution of the spectral energy density of noisy electromagnetic sources. The introduced methodology can be combined with available electromagnetic modeling tools. It is shown that the method of moments can be applied to solve noisy electromagnetic field problems by network methods applying correlation matrix techniques. Examples demonstrating the strong influence of the correlation between the sources on the spatial distribution of the radiated noise field are presented.
