周期性结构（如光子晶体、声子晶体）具有带隙特征，类桁架结构（如Kagome Lattice结构、Tetrahedron Lattice结构）有没有带隙特征？ 今天刚搜到一篇外文毕业论文，说Kagome结构没有带隙特征，真相到底是怎样的？：：：： 6.4.3 Band-gaps The band-gap behavior of the considered rectangular cylindrical grids is analyzed by considering the first Brillouin zone of the unit cell for all three grids (Fig. 72). Unfortunately,no band-gap behavior is found for any of the three grids considered (Fig. 77), over the frequency range of interest. ：：：：： 7.2.4 Band-gaps The band-gap behavior of the two considered Kagome lattice configurations is analyzed by considering the first Brillouin zone of the unit cell (Fig. 92). There is no additional symmetry in the phase constant surfaces, so the dispersion relations along the boundary M——〉P ——〉G——〉 X ——〉M must be considered. Unfortunately, no band-gap behavior was found for any of the configurations considered (Fig. 93). 有哪位高人帮忙解释一下？？    [ Last edited by 509266024 on 2010-10-22 at 13:36 ] |
