Asymptotic and exact local radiation boundary conditions (RBC) for the scalar time-dependent wave equation, ΓΏrst 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

## Abstract We define an abstract setting to treat wave equations equipped with time‐dependent acoustic boundary conditions on bounded domains of **R**^__n__^ . We prove a well‐posedness result and develop a spectral theory which also allows to prove a conjecture proposed in [13]. Concrete problems

We describe a new, efficient approach to the imposition of exact nonreflecting boundary conditions for the scalar wave equation. We compare the performance of our approach with that of existing methods by coupling the boundary conditions to finite-difference schemes. Numerical experiments demonstrat
