The plane scalar problem on the refraction of a high-frequency wave, given by its ray expansion, from a curvilinear interface of two media is considered. It is assumed that the velocity in the medium where the refracted wave propagates is larger than the velocity in the medium where the incident wave propagates. It is also assumed that, on the interface, there is a point on one side of which the ordinary refraction of the wave holds and on the other side of which the complete internal reflection of the wave occurs. An analytic expression of the wave field near this limiting point is found. Bibliography: 8 titles. |
