| Abstract: | The scattering of tlme-harmonlc acoustic waves by sound-soft obstacles leads to the exterior Dirichlet problem in homogeneous medium. The meshless method was used to solve the exterior Dirichlet problem in this paper. The paper presented a numerical result in two-dlmension, which shows that the meshless method has good accuracy compared with Nystrom method. |
