Reflection and refraction of Alfven waves by a moving flat nonuniformity in a conducting medium

The solution and structure of a magnetohydrodynamic flow in an infinite moving layer was constructed and studied by the method of integral equations of magnetohydrodynamics. The study was limited to analyzing Alfven waves. The MHD field in a flat infinite layer, perturbed by a plane wave, was represented as a finite sum of plane waves. Relations between the angles of incidence, refraction, and reflection of plane Alfven waves from a uniformly moving nonuniformity were derived. In this moving nonuniformity the angles of reflection and refraction depend not only on the angle of incidence and the parameters of the media but also on the velocity of the boundaries. The existence of a limiting angle, analogous to Brewster's angle in electrodynamics, indicated that it might be possible to build an interferometer of the Fabry-Perot type for Alfven waves.
