Abstract:

The ten conditions which must be satisfied before simple magnetohydrodynamic MHD waves can propagate in a plasma are enumerated and discussed. Assuming that all but the tenth condition are satisfied throughout the ionosphere and that the earth is a perfectly conducting plane, the propagation of MHD waves in a horizontally stratified ionosphere composed of electrons, ions, and neutrals is studied when an arbitrarily oriented plane wave is obliquely incident at the lower edge of the ionosphere. The equations governing the behavior of the field quantities are cast in the coupled form suitable for computation by means of a high-speed modern computer, but no numerical results are obtained because of the prohibitive amount of work necessary to solve the equations in the case of oblique incidence. The velocity of MHD waves is formulated.
