摘要：

For two-dimensional external wave problems, we generate exact far-field condition on a circular artificial boundary. The operator of the condition is non-local in both space and time. In order to reduce computational resources needed for its discrete counterpart, we propose a way to localise the computational formulae with respect to time.
