| Abstract: | In this paper,the band structures of the two-dimensional phononic crystals consisting of(elliptic) cylinders were calculated by using the plane wave expansion method.Comparing with that consisting of circular cylinders,it was found that larger band gap can be obtained by taking elliptic cylinders as scatters. |

| Keywords: | phononic crystal plane wave expansion method band structure |
