即使准周期性晶体(或准晶体)的晶格并不完全是周期性的,但仍具有长程有序态。这样的晶体能具备周期性晶体无法得到的对称性。中国科学院的研究人员利用准晶体独有的特点制作了具有8倍对称性的二维微波光子晶体。它有与光入射角无关的带隙。这与周期性光子晶体相反,后者由不同方 Even though the lattice of quasi-periodic crystals (or quasi-crystals) is not completely periodic, it still has long-range and orderly states. Such a crystal can have the periodic crystal can not get the symmetry. Researchers from the Chinese Academy of Sciences made a two-dimensional microwave photonic crystal with 8-fold symmetry using the unique characteristics of quasicrystals. It has a band gap independent of the angle of incidence of light. This is the opposite of periodic photonic crystals, the latter by different parties
