The physical mechanism of drift wave instability is studied from the particle point of view by following the method used by Dawson in his theory of Landau damping. The plasma particles are divided into two groups, resonant particles and non-resonant particles. Assuming that a drift wave starts initially while resonant particles are undisturbed, the trajectories of the particles are computed within the framework of linear theory. Such a drift wave of longitudinal mode is considered that propagates obliquely to a static magnetic field and in the plane normal to density gradient. Author
