Near-optimal perfectly matched layers for indefinite Helmholtz problems [PDF]
SIAM Review, 2015 A new construction of an absorbing boundary condition for indefinite Helmholtz problems on unbounded domains is presented. This construction is based on a near-best uniform rational interpolant of the inverse square root function on the union of a ...

Application of the Reflectionless Discrete Perfectly Matched Layer for Acoustic Wave Simulation
Frontiers in Earth Science, 2022 The perfectly matched layer (PML) is one of the most popular absorbing boundary conditions for simulating seismic waves. In theory, the PML can absorb incident waves at any incident angle and any frequency in a medium. However, numerical reflections will
