摘要

Our investigation mainly concerns the numerical and analytical study of nonlinear coupling of a fast magnetosonic wave (FMSW) with an ion acoustic wave (IAW). In this paper, we have proposed the FMSW as the pump wave, and its number density becomes modified in the presence of an IAW. If the ponderomotive force components of the FMSW are included in the dynamics of the IAW, the governing equations of the IAW and the FMSW jointly take the form of coupled nonlinear equations. In the numerical simulations of these equations, the localized filamentary structures and magnetic power spectra are evaluated. The intense localized structures and power spectra with different spectral indices [E(k) alpha k(-r), 3 <= r <= 4.5] in the dispersive range may be responsible for the acceleration of energetic particles ejected from the solar wind.
