| Abstract: | The results of a numerical experiment to study the effects of the sheath and the driving field on Tonks-Dattner resonance frequencies are presented. A one-dimensional, spatially-inhomogeneous plasma bounded by a sheath is numerically stimulated and driven by an external oscillating electric field. The resulting currents are studied as a function of frequency. The results are compared with the previous investigations. Even though there is general agreement of the present results with that of the previous investigators, other significant observations are made. For example, oscillations can occur within the sheath depending on the strength of the driving field and several additional resonances are observed in the high frequency region. |
