2. 1. Non-reflecting Boundary Conditions for Wave Propagation Problems

   Author : Daniel Appelö; KTH; []
   Keywords : ;

   Abstract : We consider two aspects of non-reflecting boundaryconditions for wave propagation problems. First we evaluate aproposed Perfectly Matched Layer (PML) method for thesimulation of advective acoustics. It is shown that theproposed PML becomes unstable for a certain combination ofparameters. A stabilizing procedure is proposed andimplemented. READ MORE

4. 2. Absorbing Layers and Non-Reflecting Boundary Conditions for Wave Propagation Problems

   Author : Daniel Appelö; Prof. Gunilla Kreiss; Eliane Becache; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PML; perfectly matched layer; Numerical analysis; Numerisk analys;

   Abstract : The presence of wave motion is the defining feature in many fields of application,such as electro-magnetics, seismics, acoustics, aerodynamics,oceanography and optics. In these fields, accurate numerical simulation of wave phenomena is important for the enhanced understanding of basic phenomenon, but also in design and development of various engineering applications.
