Electrostatic waves in a magnetized dusty plasma in presence of dust streaming

For a magnetized collisionless dusty plasma containing Boltzmann distributed ions and highly negatively charged micron sized dust grains having streaming velocity, a linear dispersion relation has been derived and the same has been extensively analyzed. In the nonlinear part, expression for the Sagdeev potential has been deduced. Effects of dust streaming, obliqueness (γ = cosθ where θ is the angle between the direction of propagation and the magnetic field) etc. on the profiles of Sagdeev potential have also been displayed.
