各向异性介质中折射波及其走时曲线研究

A Study on Refractive Waves and Their Travel Time Curve in anisotropic Media

利用斯奈尔定律研究各向异性介质中平界面上产生折射波的条件,得出了临界角表达形式.并对横向各向同性介质折射波条件进行了讨论,研完了单层界面上产生的折射波走时曲线,并将最后结果推广到多层界面的情形;最后给出模型计算结果,并对其作了讨论.

The conditions for generating refractive waves on the interface of anisotropic media are presented in this paper. Expressions for critical angles are obtained. Some discussions are made on conditions for refractive waves in transversely isotropic media. The travel time of refractive waves generated on single layered interface is studied. The cases in which the final results are generalized to multi — layered interface are investigated. Some computed results and necessary discussions on them are given.
