摘要:
平面波在变密度分层介质中的反射情况,已有很多著者作过研究[1,2],但由于数学上的困难,故一般选用的介质模型,不是计算烦琐就是实际情况有较大出入.本文利用了Ψσ之间有某种数学对称性这一特点,选择了一个比较简单,既富有广泛代表性又便于计算的介质模型,理论分析表明:①在高低频极限情况下,反射系数趋于菲涅尔公式.②密度参数不仅影响反射系数,而且还使折射率有所变化.
Abstract:
The reflections of the plane wave in a stratified medium with variable density have been investigated by many authors.Owing to the mathematical difficulty,generally the selected medium model may be either troublesome in calculation or quite different from the practical situation.In this paper,a medium model that is not only simple with an extensive representation but also convenient for calculation has been selected by uti lizing a specificity of mathematic symmetry between 4 and 6.
