Abstract : A review of the classical Bailey-Martyn theory of cross modulation (Luxembourg effect) is given. A theory is developed for electromagnetic waves in a plasma leading to a dispersion relation that depends explicitly on the velocity-distribution function f(q,t) of the electrons. The complex index of refraction is determined by the isotropic part, of, f, and a formula for the time independent part of f is derived. The time dependent part of the function is reduced to a problem of determining the solution of a pair of simultaneous second order differential equations. Next follows a detailed discussion of the coupled pair of (quasi hypergeometric) differential equations. The magnetohydrodynamic interaction of a partially ionized gas with electromagnetic waves is considered and the resulting dispersion relation illustrates the coupling between mechanical and electromagnetic waves.
