REFLECTION AND REFRACTION OF WEAK HYDROMAGNETIC DISCONTINUITIES
Technical Report

OSTI ID:4799624
The refleciion and refraction of weak hydromagnetic disturbances at surfaces of discontinuity in a medium is studied. It is shown that the introduction of an appropriate set of direction angles for the unperturbed magnetic field on each side of thc discontinuity makes poossible both a simplification of laws relating to the reflection and refraction of Alfven waves, and a simple graphical method for determining the real angles and speeds at which the reflected and refracted waves emerge. The relationship of the graphical procedure to Huygens' construction is discussed. Application of the theory is made to several two-dimensional steady-flow problems and to the problems of reflection and refraction at a rigid infinite conductor and at a contact discontinuity. (auth)
