In the present paper, the dispersions and Landau damping of the Langmuir waves and ion sound waves in the κ-deformed Kaniadakis distributed plasma system are investigated within the plasma kinetic theory regimes. The results show that the peculiarities of the dispersions and Landau damping of both the Langmuir waves and ion sound waves depend on the parameter κ of the distribution function. For Langmuir waves, the dispersion is enhanced, while the Landau damping is suppressed by κ. On the contrary, for ion sound waves, both the dispersion and Landau damping are increased by κ. As expected, the results of the Maxwellian case are recovered perfectly when κ = 0.
