多层平面几何形状的空间域格林函数被转换成具有格林函数的谱域表示的两级近似的封闭形式。与原始的一级近似相比，这种方法非常稳健并且速度更快。此外，它不需要预先研究格林函数的谱域行为来决定近似技术的参数，并且它可以同样轻松地应用于二进格林函数的任何分量。
Spatial-domain Green's functions for multilayer, planar geometries are cast into closed forms with two-level approximation of the spectral-domain representation of the Green's functions. This approach is very robust and much faster compared to the original one-level approximation. Moreover, it does not require the investigation of the spectral-domain behavior of the Green's functions in advance to decide on the parameters of the approximation technique, and it can be applied to any component of the dyadic Green's function with the same ease.
