English Abstract:
Numerical simulation of the coupled normalized equations guided by the 3-D kinetic Alfvén wave (KAW) and slow magnetosonic wave dynamics in the intermediate beta plasma have been demonstrate in the present study. We have examined the localization/filamentation and power spectrum of 3-D kinetic Alfvén wave for this nonlinear interaction. Pump KAW exerts a ponderomotive force on the slow magnetosonic wave and thereby results in localization of the wave. The coupling between KAW and slow magnetosonic wave has been studied numerically and the results were found to be consistent with the observation of THEMIS spacecraft in magnetopause.
