The problem of wave propagation in a warm magnetoplasma in the presence of random density fluctuations is studied. Using a perturbation technique similar to the renormalization procedure in field theory, a dispersion relation for plane coherent wave propagation is derived. For propagation along the magnetic field, the coherent longitudinal and transverse modes are found to be independent. But there is coupling among the modes for the random waves scattered by the irregularities. The coupling is strong for short correlation length of the turbulence. Attenuation constants for the coherent waves are obtained, and the effect of random scattering on the Faraday rotation phenomenon is discussed.
