Copyright policy )Asymmetric PML for the absorption of waves. Application to mesh refinement in electromagnetic Particle-In-Cell plasma simulations
We present an extension of the B erenger Perfectly Matched Layer with additional terms and tunable coecien ts which introduce some asymmetry in the absorption rate. We show that the discretized version of the new PML oers superior absorption rates than the discretized standard PML under a plane wave analysis. Taking advantage of the high rates of absorption of the new PML, we have devised a new strategy for introducing the technique of Mesh Renemen t into electromagnetic Particle-In-Cell plasma simulations. We present the details of the algorithm as well as a 2-D example of its application to laser-plasma interaction in the context of fast ignition.
