  Magnetowave induced plasma wakefield acceleration (MPWA) in a relativistic
astrophysical outflow has been proposed as a viable mechanism for the
acceleration of cosmic particles to ultra high energies. Here we present
simulation results that demonstrate the viability of this mechanism. We invoke
the high frequency and high speed whistler mode for the driving pulse. The
plasma wakefield so induced validates precisely the theoretical prediction.
This mechanism is shown capable of accelerating charged particles to ZeV
energies in Active Galactic Nuclei (AGN).
