In the study of wave propagation in a warm magneto‐ionic plasma, the fluid equations are usually supplemented by the equation of state where the pressure is assumed to be isotropic. This model appears to be a good approximation only for a collision‐dominated regime. In this paper, the third moment equation derived from the Boltzmann‐Vlasov equation is used instead of the equation of state. By following the Chew‐Goldberger‐Low theory, the dispersion relation for plane wave propagation can be determined under the adiabatic condition, for strong magnetic field, and without assuming isotropic pressure. Discussions of propagation characteristics under a few special conditions are also included.
