A recursive sequence of radiation boundary conditions ยฎrst given by Hagstrom and Hariharan [Appl. Numer.

Asymptotic and exact local radiation boundary conditions (RBC) for the scalar time-dependent wave equation, รฟrst derived by Hagstrom and Hariharan, are reformulated as an auxiliary Cauchy problem for each radial harmonic on a spherical boundary. The reformulation is based on the hierarchy of local b

Recently, perfectly matched layer (PML) as an absorbing boundary condition has found widespread applications. The idea was first introduced by Berenger for electromagnetic waves computations. In this paper, it is shown that the PML equations for the linearized Euler equations support unstable soluti
