摘要: 本文系统的研究了由圆柱介质构成的二维正方结构、三角形结构、六角形结构，在折射率分别为n = 1.5 (玻璃)，1.8 (石墨)，2.5 (石墨)，圆柱之间相切和不相切的条件下的带隙，得到了完整的带隙分布；通过把两种不同的正方形结构组合，以及三角形结构和六角形结构组合，得到组合后的带隙，发现两种不同的正方形结构组合后，这两种结构的带隙在组合后都得到完全的再现；三角形和六角形结构组合后，三角形结构的带隙得到完全再现，六角形结构的带隙得到部分再现。
Abstract: The two-dimensional tetragonal structure, triangular structure, and hexagonal structure composed of cylindrical dielectric were studied. The refractive index is n = 1.5 (glass), 1.8 (graphite), 2.5 (graphite) respectively. Between the cylinder is tangent or not tangent, the paper got the complete band gap distribution. Through the two different square structures combination, and triangular and hexagonal structure combination, the paper got band gap after combination, and found that after the combination of two different square structures, the gap was fully reproduced. After triangular and hexagonal structure combination, the band gap in triangular structure was completely reappeared; band gap of hexagonal structure was partly reappeared.
