dc.description.abstractProblems of linear time-dependent dispersive waves in an unbounded domain are con- sidered. The infinite domain is truncated via an artificial boundary B. A high-order Non-Reflecting Boundary Condition (NRBC) is imposed on B, and the problem is solved by a Finite Difference (FD) scheme in the finite domain. The sequence of NRBCs proposed by Higdon is used. However, in contrast to the original low-order implementation, a new scheme is devised which allows the easy use of a Higdon-type NRBC of any desired order. In addition, the problem is considered for a stratified media. The performance of the scheme is demonstrated via numerical example.en_US
