Abstract
Abstract. Three-dimensional hybrid simulations have been carried out to verify the hypothesis of simultaneous multi-channel decay of
a large-amplitude Alfvén wave in a
low-beta plasma, e.g., in the shock-upstream region or the solar corona.
Obliquely propagating daughter modes
are excited along the perpendicular direction to the mean magnetic field at the same parallel wavenumbers and frequencies as the daughter modes driven by the field-aligned decay. We find that
the transversal spectrum of waves
is controlled by the multi-channel coupling of the decay process
in low-beta plasmas and
originates in the dispersion state of the shear Alfvén wave.
