摘要：

We have calculated the band structure of acoustic and elastic waves propagating in two dimensional periodic fluid or solid systems respectively. In fluids, gaps are obtained easily, in contrast to the case of solids, where a large density mismatch is required. A system consisting of Au cylinders embedded in a Be host exhibits a narrow gap.
