摘要
It is shown that a magnetized dust-ion plasma can support a new low-frequency circularly polarized dispersive electromagnetic wave, whose frequency is proportional to the wave electric field amplitude. In the new wave, inertia comes from the dust mass, whereas the restoring force is associated with the medium polarization due to relativistic ion motion. The implication of our investigation to cosmic plasmas is pointed out.
