Abstract:

Based on the calculation method of grating structure , the authors have developed an eigen-mode matching theory to study the propagation of classic waves in periodic systems. The proposed method has been applied to the investigations of phononic crystals with solid/ solid , liquid/liquid and air/rigid body types , and has been expanded to the investigation of frequency-band structure and transmission properties of liquid surface wave with topology bottom. The effectiveness of the proposed theory is verified by numerical results.

Key words: phononic CIγstal, liquid surface wave, eigen-mode matching theory
