Frequency shift of a nonlinear plasma wave and its initial damping
Abstract
For large wave amplitudes, the frequency shift of a nonlinear plasma wave and its initial exponential damping are found to be approximately proportional to the square of the initial wave amplitude. Extensive Vlasov computations are in essential agreement with recent experimental results for wavenumber shifts and initial nonlinear dampings obtained at large amplitudes.
