Conventional δf -particle simulations of electromagnetic perturbations with finite elements

The possibility of electromagnetic particle-in-cell simulations with a conventional δf approach is shown in slab geometry using finite elements. Both the ion-temperature-gradient driven mode and the shear Alfvén wave are reproduced and benchmarked with the analytical linear dispersion relation. Particularly, the Alfvén wave is simulated successfully at the limit k ⊥ →0 .
