  Generation of radio bursts in CME foreshock regions and turbulent cascades in
the solar wind are assumed to be results of three-wave interaction processes of
dispersive plasma modes. Using our Particle in Cell code ACRONYM, we have
studied the behaviour of kinetic wavemodes in the presence of beamed electron
populations, with a focus on type II radio burst emission processes. We discuss
the numerical challenges in generating and analyzing self-consistently evolving
wave coupling processes with a PiC-Code and present preliminary results of said
project.
