Abstract : The interaction of a plane, electromagnetic wave with a flat, uniform, freespaceplasma interface in a static magnetic field has been considered for arbitrary angles of incidence. The dispersion relation for the plasma is a complex quartic equation which reduces to a quadratic if the static magnetic field and plasma boundary is orientated along any one of the rectangular coordinate axes. (These axes need not simulataneously be the same for the plasma and the magnetic field.) The analysis is greatly simplified by writing the boundary conditions in terms of the fields in the plasma, and for the model considered a rigorous solution has been obtained. The solution indicates that two waves can be simultaneously supported by the plasma. These two waves are, in general, elliptically polarized, plane, and nonhomogeneous. Either wave can be launched by a suitable elliptically polarized, plane incident wave. Superposition of these waves, each of which gives one plasma wave, is a simpler procedure than superposing plane or circularly polarized waves, each of which gives rise to two waves. Although the field vectors associated with the two waves in the plasma can be superimposed, the energy carried in each wave cannot since the two waves interfere within the plasma. (Author)
