Nonlinear electron oscillations in a viscous and resistive plasma
Nonlinear electron oscillations in a viscous and resistive plasma
New non-linear, spatially periodic, long wavelength electrostatic modes of an electron fluid oscillating against a motionless ion fluid (Langmuir waves) are given, with viscous and resistive effects included. The cold plasma approximation is adopted, which requires the wavelength to be sufficiently large. The pertinent requirement valid for large amplitude waves …
