摘要

本文讨论了孔洞周期超表面的色散图，这些色散图是通过分析孔洞周期超表面的原始单细胞或超级单体得到的。特别地，研究了超级单体的色散图与原始单位细胞的标准图之间的联系。在由两个或三个方形单体组成的矩形超级单体的情况下，解释和举例说明了其他“异常”模式的出现。

Understanding the Dispersion Diagrams of Two-Dimensional Supercells

This paper discusses the dispersion diagrams of holey periodic metasurfaces, which have been computed by analyzing either the primitive unit cell or a supercell of the structure. Particularly, the connection of the dispersion diagram of the supercell to the standard diagram of the primitive unit cell is investigated. The appearance of additional “anomalous” modes is explained and exemplified in the case of a rectangular supercell composed of two or three square unit cells.
