作者 康寿万 《北方交通大学学报》 CSCD 北大核心 1993年第1期8-14,共7页
提出了一种研究渐变波导中场的分布的新方法,采用保角变换方法,把一个具有阶跃折射率的平板渐变波导,变换成一个厚度不变但折射率沿纵向为连续变化的平板波导.方便地求出波导中场的分布,再经过反变换,得到在渐变波导中的场.

In the case of SV- or SH-wave oblique incidence,the reflection and refraction of the second-order bulk waves resulting from a plane boundary between two solid media are investigated and the mathematical expressions of them are given.It is shown that an SH-wave incidence is absolutely necessary to an overall knowledge of the relationship between the TOEs for isotropic solid.The importance of both contributions of the nonaccumulation waves and the effects of the boundary surface are indicated by numerical computation. 展开更多
