我们给出了声波在流体中由固体球体组成的周期性复合材料中传播的结果。结果表明，对于流体主体材料组合中的固体散射体，广泛使用的平面波方法不足以产生精确的结果，需要一种新的方法。我们的能带结构结果是基于著名的Korringa-Kohn-Rostoker方法的扩展的多重散射方法得到的。[S0163-1829(99)04841-9]。
We present results for acoustic wave propagation in periodic composites consisting of solid spheres in a fluid host. We show that for solid scatterers in fluid host material combinations the extensively used plane-wave method is inadequate to produce accurate results and a new approach is required. Our band-structure results are obtained by using a multiple-scattering approach based on an extension of the well-known Korringa-Kohn-Rostoker method. [S0163-1829(99)04841-9].
