Consider space to be separated into two semi-infinite regions by a rigid boundary. On one side lies medium A--a perfect, rigid, dielectric, with electric permittivity € and magnetic permeability µ. On the other side is medium B; a perfect, fluid, perfectly conducting, also with magnet permeability µ. Throughout all spaces exist a uniform static magnetic field H.
Now such a fluid as medium B is capable of supporting a magnetohydrodynamic (MHD) wave; and of course a perfect dielectric will support an electromagnetic (EM) wave. Suppose then, that a uniform plane EM wave in medium A is incident at arbitrary angle on the boundary. Will the EM wave generate an MHD wave at the boundary? If so, to what degree? In what manner will the interaction between the EM wave and the MHD fluid be dependent on the characteristics of the media and on the angle of incidence of the EM wave?
