A one-dimensional form of the equation of motion with forcing and dissipation is formulated in the spectral domain and used to make long term integrations from which the spectral distribution of the k...
Electron acoustic solitary waves with non-thermal distribution of electrons
Electron acoustic solitary waves non-thermal distribution of electrons
2009/11/11
Electron-acoustic solitary waves are studied in an unmagnetized plasma consisting of non-thermally distributed electrons, fluid cold electrons and ions. The Sagdeev pseudo-potential technique is used ...
