The dispersive effects are significant if the modulation frequencies Ω are comparable to or greater than the ion cyclotron frequency ωci. It is shown that in this case there are four unstable branches: the long-wave modulational instability and three others with much larger growth rates. At Ωωci the latter correspond to fast magnetic sound, Alfvén and slow magnetic sound branches. Copyright © Cambridge University Press 1989 Karpman V. I.
