In this paper we propose a strategy to suppress the recurrence effect present
in grid-based Vlasov solvers. This method is formulated by introducing a cutoff
frequency in Fourier space. Since this cutoff only has to be performed after a
number of time steps, the scheme can be implemented efficiently and can
relatively easily be incorporated into existing Vlasov solvers. Furthermore,
the scheme proposed retains the advantage of grid-based methods in that high
accuracy can be achieved. This is due to the fact that in contrast to the
scheme proposed by Abbasi et al. no statistical noise is introduced into the
simulation. We will illustrate the utility of the method proposed by performing
a number of numerical simulations, including the plasma echo phenomenon, using
a discontinuous Galerkin approximation in space and a Strang splitting based
time integration
