Theoretical models for resonance oscifiations of inhomogeneous plasmast

The resonance oscifiations of low temperature, bounded, non-magnetized in-homogeneous plasmas are studied using different methods of solving the linearized Vlasov—Maxwell equations. A low-temperature expansion method of solving the orbit-integral solution of the Vlasov equation is compared to fluid descriptions of the plasma using the truncated moment equations. Numerical results for a one-dimensional plasma slab show qualitative agreement but some quantitative discrepancies.
