Application of the Reflectionless Discrete Perfectly Matched Layer for Acoustic Wave Simulation
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

The Fokker–Planck Equation with Absorbing Boundary Conditions [PDF]
We study the initial-boundary value problem for the Fokker-Planck equation in an interval with absorbing boundary conditions. We develop a theory of well-posedness of classical solutions for the problem. We also prove that the resulting solutions decay exponentially for long times.

Absorbing Boundary Conditions for Linear Gravity Waves [PDF]
The authors construct, analyse and implement a family of absorbing boundary conditions for linear gravity waves in two dimensions. The mathematical properties of the water waves' model are nicely explained and compared with the properties of the acoustic wave equation. The theoretical analysis is exemplified with several numerical experimentation.
