论文摘要
周期性结构是一种超材料的类型，其中物理特性不仅取决于单元细胞的细节，还取决于单位单元格的布置和相互作用。在常规的工程结构中，每个晶胞与相邻的细胞相互作用。为周期性工程结构中的振动和波传播分析而开发的方法仅考虑最近的邻居相互作用。仅相互作用的这种系统的分散曲线已经进行了广泛的研究。超材料的特性取决于单位细胞与其他细胞的相互作用。进一步的相互作用，特别是在最接近的邻居之外的相互作用，这意味着更复杂的频带结构和波浪行为。在本文中，已经研究了此类结构的示例类别，其中静电力是驱动力。在本文中，已经研究了影响这些周期性结构的特性，例如弹性力。这种结构的一个有趣的特性是，可以通过更换电压来调整此类超材料的带结构。
Periodic structures are a type of metamaterial in which the physical properties depend not only on the details of the unit cell but also on how unit cells are arranged and interact with each other. In conventional engineering structures, each unit cell interacts with adjacent cells. Methods developed for vibrational and wave propagation analysis in periodic engineering structures consider only nearest-neighbor interactions. The dispersion curves of such systems, in which only adjacent cells interact, have been extensively studied. Metamaterial properties depend on the interactions of a unit cell with other cells. Further interactions, and specifically, interactions beyond the closest neighbors, imply a more complex band structure and wave behavior. In this paper, an example class of such structures, in which electrostatic forces are the driving force, has been investigated. In this paper, properties affecting these periodic structures, such as elastic forces, have been investigated. An interesting property of such structures is that the band structures of such metamaterials can be tuned by changing electric voltages.
