Grain Oscillations Induced By Electrode Voltage Modulation

We have analyzed the dynamics of a single grain immersed in a plasma sheath, under low pressure conditions. The influence on the grain dynamics of an electrode potential modulation have been analytically and numerically explored. For the first time the effects of this excitation technique on the plasma sheath environment have been theoretically analyzed, and the grain motion resulting uom the sheath modification induced by the external driver have been studied. Comparison with experimental data inferred from published investigations is also presented.
