Wave propagation in drifting strong magnetoplasma under Grad's thirteen-moment approximation

Earlier work on wave propagation in drifting warm plasma and in drifting weak magneto-plasma under Grad's thirteen-moment approximation is here extended to wave propagation in strong magnetoplasma under the same approximation. In this study, the magnetic field is considered to be of sufficient strength to dominate and suppress the randomising effect of collisions. Consequently the electron pressure is treated as a tensor resulting in thermal conductivity and viscosity matrices as against scalars in the earlier work. The nature of wave propagation is reported in detail for various orientations of magnetic field and drift. The usual splitting of the electromagnetic mode is observed, but the splitting of viscous modes which occurs in weak magnetic fields is found to be completely absent in strong magnetic fields. It is further found that these viscous modes have a large attenuation coefficient in strong magnetic fields and consequently become evanescent.
