RÉSUMÉ

The problem of reflection and refraction of a narrow wave beam from the boundary of two isotropic dielectric half-spaces is considered. The asymptotic expressions for the fields in the upper and lower half-spaces are obtained. As an example, the case of the Gaussian beam incident at an angle greater than the total internal reflection angle is considered. The field of the surface wave excited by the beam is found.
