Frequency oscillation of whistler wave in magnetic reconnection
View through CrossRef
A 2.5-D PIC kinetic simulation code has been run for excitation of
whistler wave and wave-particle interaction process in symmetric
magnetic reconnection. The whistler wave is important to the energy
release and transfer, which move faster for a perturbation of the
magnetic field because of electrons smaller mass during magnetic
reconnection. Our simulations suggest that whistler wave can be excited
in separatrices line region of magnetic reconnection, and the frequency
range of whistler wave is in the lower band (Ωlh< Ω
<0.5Ωce). Furthermore, the frequency of whistler wave is
oscillation with the change of space position. And the power amplitude
of whistler wave also increases with the increasing of reconnection
rate. On the other hand, whistler wave can transfer energy to electrons,
which increases electrons energy by wave-particle interaction.
