A perfectly matched layer for the absorption of electromagnetic waves
TL;DR: Numerical experiments and numerical comparisons show that the PML technique works better than the others in all cases; using it allows to obtain a higher accuracy in some problems and a release of computational requirements in some others.

On Absorbing Boundary Conditions for Linearized Euler Equations by a Perfectly Matched Layer
TL;DR: In this article, a perfectly matched layer (PML) is proposed for absorbing out-going two-dimensional waves in a uniform mean flow, governed by linearized Euler equations, and the theoretical reflection coefficients at an interface between the Euler and PML domains are zero, independent of the angle of incidence and frequency of the waves.
