Impact of charged dust on the propagation of driven low frequency, electrostatic fluctuations in a magnetized plasma

The role of charged, solid particulate matter (i.e., "dust"’ in plasmas has been considered for several decades. However, beginning with observations of structures in the dust tails of comets and the Voyager observations of radial structures ("spokes"’ in Saturn’s rings, the role of charged dust in the solar system led to the emergence of the field of "dusty" (alternatively, "complex"’ plasmas. Since the early 1990’s there has been a complementary effort in the area of laboratory dusty plasmas that has, over almost four decades, led to the observation of numerous types of plasma and dusty plasma behavior – ranging from appearance of strongly-coupled, self-organized dusty plasma crystals to new types of collective, dust-driven modes, such as the dust acoustic and dust density waves.
