Absorbing boundary condition for scalar-wave propagation problems in infinite media based on a root-finding algorithm

In this study, we propose a new approach for development of absorbing boundary conditions for scalar-wave propagation problems in infinite media based on a root-finding algorithm for the solution of the exact wave dispersion relation. We select the Newton–Raphson method as the root-finding algorithm...
