Full Record; … most common religion in russiaWebbIt is shown that finite amplitude Langmuir waves might be produced due to the usual two-stream (beam-plasma) instability under certain conditions. Langmuir waves may saturate by beam trapping and attain finite amplitudes. Large amplitude Langmuir waves can nonlinearly interact with dust acoustic waves due to the parametric process. most common religions in czech republicWebb1 sep. 2010 · The emission of Langmuir waves in the form of small-scale localized electrostatic bursts have been observed directly in waveform data in many space plasma environments, such as solar wind, auroral region and polar cap. miniature dollhouse fenceWebb30 dec. 2024 · Abstract. A Gyrating ion beam traveling through a plasma cylinder comprising of electrons, positive ions , and heavy negative ions, through Cerenkov interaction, drive IAWs (ion-acoustic waves) to unstable mode.

Our objective here is to show that such a two-component dusty plasma supports dust-Langmuir and dust-acoustic waves. The latter in the nonlinear regime propagate in the form of localized negative potentials. most common religion zimbabweWebb1 maj 1994 · Three wave modes are considered; the ionacoustic wave, the electrostatic ion cyclotron (EIC) wave, and the Langmuir wave. We find that the dust charge variation and the wave field have a phase shift relative to each other which influence the wave dispersion and normally lead to an energy transfer between the waves and the plasma. miniature donkey carts wagonsWebbThe nonlinear propagation of coupled Langmuir and dust-acoustic waves in a multi-component dusty plasma is considered. The coupled mode propagation is described by a Schrodinger{Boussinesq system, which reduces to the Schr¨ odinger{KdV sys-¨ tem for unidirectional wave propagation.
