Abstract
We propose an exact boundary condition on the circular artificial boundary for outgoing waves described by the two-dimensional wave equation. The boundary condition is non-local in both space and time, nevertheless its discrete counterpart has local computational formulae with respect to time. Numerical tests demonstrate a high accuracy while using a discrete counterpart of the condition. Copyright © 2000 John Wiley & Sons, Ltd.
