Amplitude dispersion of standing electron plasma waves
Abstract
Nonlinear corrections to the linear dispersion relation for plasma waves are calculated from the macroscopic equations by means of a multipletime scale expansion. For standing waves a nonvanishing frequency shift is obtained in the longwavelength limit when a secondorder steadystate ion density modulation is included.
