Abstract
Wave propagation in a dusty magnetised plasma
at frequencies below and of the order of the ion-cyclotron frequency,
and with a non-zero electron temperature is considered. The
general dispersion relation for waves propagating at an arbitrary angle
with respect to the external magnetic field and for finite ion-cyclotron
frequency is derived and discussed.
Modification of the Alfven resonance absorption mechanism due to the presence
of a finite proportion of the negative charge of the plasma on stationary dust grains
is investigated.
