The effects of Gaussian size distribution dust particles in a complex plasma

Investigations for a dusty plasma with many different dust grain species are adopted, which varies self-consistently with the system parameters. Two cases have been studied. One is that the dust size distribution is given by Gaussian distribution. The other is that there is only one kind of dust grains (mono-sized dusty plasma) whose size is the average one of Gaussian distribution. The comparisons between them have been made and it is found that the linear phase velocity is different.
