%X In this paper, based on natural boundary reduction suggested by Feng and Yu, an nonoverlapping domain decomposition method with its discretization is presented for the exterior problem of 2-D Helmholtz equation. The convergence of the D-N alternating algorithm and its discretization are studied. Some numerical results are given.
