随机不均匀媒质中的几何光学近似方法

The Geometric Optics Method in Random Inhomogeneous Media

极据惠更斯-菲涅尔原理指出几何光学适应性判据是相邻两个相位面之间任意两条射线互不相交。在此基础上得到了电波斜进入平面分层随机不均匀散射媒质情况下，几何光学近似方法的适用条件。首次指出随机不均匀煤质中的几何光学近似方法适用范围显著地依赖于煤质介电常数的涨落。

A new criterion of geometric optics method validity in random refractive media has been developed. The criterion is descrital as no ray intersections between any two adjacent wave fronts. lt hais been shown that the validity range of geometric optics method strongly depends on the nuctuation of media dielectric Gonstant.
