An algorithm is presented to treat the absorbing boundaries for the time-domain finite-difference method. With this approach, the leading order error of the conventional local absorbing boundary conditions can be cancelled by a simple algorithm, so that the absorbing quality of the boundary conditions can be greatly improved. The authors concentrate on the local boundary conditions which represent the field values on boundary nodes by several field values inside (and possibly on) the boundary.<>
