论文摘要
我们通过对不同构型之间的比较研究揭示了基于INERTER的弹性超材料的独特和基本优势。当嵌入的INERTER连接到两端的基质材料时，超材料在超低频率中形成带隙的明确优势（等效地是超长波长 - 机制），其中单位细胞大小可以比操作波长小四个或更多的数量级。此外，我们在一个和二维的参数研究铺平了设计下一代超材料以缓解结构振动的道路。
We reveal the unique and fundamental advantage of inerter-based elastic metamaterials by a comparative study among different configurations. When the embedded inerter is connected to the matrix material on both ends, the metamaterial shows definite superiority in forming a band gap in the ultra-low frequency -- equivalently the ultra-long wavelength -- regime, where the unit cell size can be four or more orders of magnitude smaller than the operating wavelength. In addition, our parametric studies in both one and two dimensions pave the way towards designing next-generation metamaterials for structural vibration mitigation.
