A practical analytical model based on the good old electrostatic probe theory has been developed for the dust-charging process . Using this model and numerical calculations, several earlier works on dusty plasmas, such as linear and nonlinear waves, plasma-wall interaction, and dust expansion, have been improved. By means of both the simple and improved models, problems of applicational interest are also studied.

Langmuir, ion-acoustic, and light waves in dusty plasmas [1-8]

Effect of impurity or dust particles on other plasma waves [11-13]

Expansion of low-temperature dust particles in a plasma [9]

Effect of dusts on plasma-wall interaction [10]

Double layers near walls


Exact solutions for electrostatic waves in cold plasmas confined by dielectrics [14-17]

Finite amplitude nonlinear surface waves at plasma boundaries [18-25]

Radiation arising from the plasma-maser effect [26,27]

Dissipative effects of collisions, ionization and electron mass variation on linear and nonlinear volume and surface waves in low-temperature plasmas [28-36]

Some of the above works have been included in a Physics Report [36] .
