Plasma oscillation — Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals. The frequency only depends weakly on the wavelength. The quasiparticle… … Wikipedia
Plasma parameters — define various characteristics of a plasma, an electrically conductive collection of charged particles that responds collectively to electromagnetic forces. Plasma typically takes the form of neutral gas like clouds or charged ion beams, but may… … Wikipedia

Plasma scaling — The parameters of plasmas, including their spatial and temporal extent, vary by many orders of magnitude. Nevertheless, there are significant similarities in the behaviors of apparently disparate plasmas. It is not only of theoretical interest to … Wikipedia
Upper hybrid oscillation — An upper hybrid oscillation is a mode of oscillation of a magnetized plasma. It consists of a longitudinal motion of the electrons perpendicular to the magnetic field with the dispersion relation:omega^2 = omega {pe}^2 + omega {ce}^2 + 3 k^2 v… … Wikipedia
Onde de plasma — En physique, une onde de plasma est une propagation concertée de particules et de champs. Un plasma se comporte comme un fluide, quasineutre et conducteur. Dans les cas les plus simples, il se compose d électrons et d une seule espèce d ions.… … Wikipédia en Français
