Abstract
Propagation of small amplitude waves perpendicular to the magnetic field in a two component magnetoactive, unbounded warm plasma having arbitrary mass ratio has been examined using Maxwell's equations for the electromagnetic field and the first three moment equations for each component. The full pressure tensor equation (neglecting the heat flow tensor) has been used and the effect of momentum and pressure relaxation mechanisms has been included in the analysis. Dispersion relations for pure transverse waves are obtained and discussed in detail for both low and high frequency propagation. The effect of thermal motions and collisions is examined for transverse and coupled waves. It has been found that the pressure relaxation mechanism contributes significantly in the damping of oscillations at the harmonic cyclotron frequency.
