计算了水中由钢柱组成的二维声子晶体的相位常数面,预测了声波传播的方向性。在远离带边态的通带频率处可以获得高方向性的声源。这一观察结果与前两种方法中的观察结果有很大不同,前两种方法中的一种是由于二维声子晶体中的高密度带边态,另一种是由于二维声子晶体中的谐振腔态。通过24 × 24单元有限结构的声场分布验证了该预测的正确性。
The phase constant surfaces of two-dimensional phononic crystals consisting of steel cylinders in water are calculated to predict the directivity of acoustic wave propagation. A highly directional acoustic source can be obtained at a pass band frequency far away from the band edge states. This observation is quite different from those in the two former approaches, where one is due to the high density of band-edge states and the other is due to the resonant cavity state in two-dimensional phononic crystals. The prediction is validated by the acoustic field distributions of a finite structure with 24 × 24 unit cells.
