数值研究了Lamb波在由钨（B）和硅树脂（A）按Fibonacci序列排列的一维准周期复合薄板中的传播。发现兰姆波的带隙结构与体波的带隙结构有很大的不同。与准周期体光子晶体和声子晶体不同的是，它的带隙分裂与晶体层数无关。讨论了可能的应用。
The authors study numerically the propagation of Lamb waves in one-dimensional quasiperiodic composite thin plates made of tungsten (B) and silicon resin (A) arranged according to a Fibonacci sequence. It is found that the band-gap structures of Lamb waves are very different from those of bulk waves. The split of band gaps is independent of the number of layers, which is different from the quasiperiodic bulk photonic and phononic crystals. Possible applications are discussed.
