KEEN waves [1] provided a challenging test case for Vlasov Poisson numerical solvers since they involve highly non stationary, multiple-harmonic self-organized kinetic states. They require high resolution in the phase space region around the phase velocity of the drive wave. Different interpolation strategies are discussed and compared to classical cubic splines.
