Owing to their ability to model the physics of low-pressure plasmas away from thermodynamical equilibrium, particle-in-cell (PIC) techniques have become one of the tools of choice to simulate the operation of many plasma devices. This trend is reinfo

L’intérêt d’utiliser des particules chargées accélérées à de grandes vitesses pour propulser un engin spatial a germé dans la tête de C. Tsiolkovski (1857-1935), qui a posé les fondements de l’astronautique dans son ouvrage de 1903. I

In this article, we propose and analyse Particle-In-Cell (PIC) methods embedding sparse grid reconstructions such as those introduced in Ricketson and Cerfon [Plasma Phys. Control. Fusion 59 (2017) 024002] and Muralikrishnan et al. [J. Comput. Phys.

The Particle-In-Cell (PIC) technique couples a Lagrangian method to describe charged particles transport with Eulerian approach to resolve Maxwell’s equations. They are extensively used in the context of low temperature plasmas. For such applicatio

The use of a particle-in-cell (PIC) algorithm with an explicit scheme to model low temperature plasmas is challenging due to computational time constrains related to resolving both the electron Debye length in space and the inverse of a fraction of t
