| 摘 要： | 采用平面波展开法计算了浅水表面波在底部按周期性钻孔结构下的能带，找到了完全带隙的出现.通过考虑方形孔按正方晶格排列、圆形孔按正方晶格和六角晶格排列等三种钻孔模型，发现带隙的数量、宽度、频率、位置与孔的面积、形状、方位角及其排列晶格等都有关.且这些规律与光子/声子晶体的情况相类似.

| Abstract: | The band structures of shallow water surface wave propagating over a periodically perforated bottom are calculated by the plane wave expansion method，and complete band gaps appear. Through considering three drilling patterns （square holes arrayed in square lattice，circular holes arrayed in square and hexagonal lattices），we find that the number，width，frequency and location of band gaps are related to the area，shape，orientation of drilled holes and the lattice. These rules are similar to those in photonic/ phononic crystals. |
