Model for nonlinear evolution of localized ion ring beam in magnetoplasma
(AIP Publishing, 2012-06-01)
An electrostatic hybrid model, which investigates the nonlinear evolution of a localized ion ring beam in a magnetoplasma, is described and applied to the generation and evolution of turbulence in the very low frequency ...
Early time evolution of a chemically produced electron depletion
(American Geophysical Union, 1995-01-01)
The early time evolution of an ionospheric electron depletion produced by a radially expanding electron attachment chemical release is studied with a two-dimensional simulation model. The model includes electron attachment ...
Three dimensional character of whistler turbulence
(AIP Publishing, 2010-05-01)
It is shown that the dominant nonlinear effect makes the evolution of whistler turbulence essentially three dimensional in character. Induced nonlinear scattering due to slow density perturbation resulting from ponderomotive ...
Early time evolution of negative-ion clouds and electron-density depletions produced during electron-attachment chemical-release experiments
(American Geophysical Union, 1994-01-01)
Two-dimensional electrostatic particle-in-cell simulations are used to study the early time evolution of electron depletions and negative ion clouds produced during electron attachment chemical releases in the ionosphere. ...
Low Frequency Oscillations in A Plasma with Spatially Variable Field-Aligned Flow
(AIP Publishing, 2002-05-01)
The effects of a transverse gradient in the plasma flow velocity parallel to the ambient magnetic field are analyzed. A transverse velocity gradient in the parallel ion flow, even in small magnitude, can increase the ...
