Waves in a bounded two component electron-dust plasma

Taking into account the boundary, the dust charge variation, the dust size and particle density effects, waves in a two component electron-dust plasma, bounded by a cylindrical domain, are presented. The dispersion relation for the waves is obtained and investigated analytically. Some limiting cases are also discussed. It is shown that the mentioned effects have a strong influence on the dispersion properties of the waves. The finite geometry not only modifies the frequencies of the excited modes, but it also has significant influence on the damping rate of the long waves
