Abstract:
The propagation of low-frequency electromagnetic waves of small amplitude in a low-pressure dust plasma is considered
in the paper. Dust is considered to be cold and has both a transverse and longitudinal velocity relative to the direction of the
external magnetic field. The fourth-degree dispersion equation for the phase velocities of waves is analytically studied. Limits
on the unperturbed plasma parameters with stable homogeneous state of plasma are obtained. It is shown that in the absence of
sufficiently large values of the velocity component of the dust component along the magnetic field, the homogeneous state of
plasma is unstable concerning small perturbations.
Keywords:dust plasma, small amplitude waves, dispersion equation, the stability of a homogeneous plasma state.
