修正的几何光学近似方法在平面分层媒质中的运用

The Use of a Modified Geometric Optics Method in Stratified Media

利用修正的几何光学近似方法，在电波以电离层最大接收频率斜入射情况下，首次计算得到了包括抛物线层、尖劈形层、三角形层在内的一种电离层平面分层模型的反射系数和透射系数统一的、精确的解析表达式。并对得到的结果进行了讨论。

An accurate analytical expression for renection and transmission coefficients for a stratified media model was derived by using a modified geometric optics method when the incident radiowave frequency equals to the critical frequency of the media. The media model includes parabolic,linear, and wedge-like models. Some discussions about the result were given.
