| 摘 要： | 用平面波展开法研究二维函数光子晶体介质柱介电常数不同的线性函数形式对横电(TE)波和横磁(TM)波带结构的影响. 数值计算结果表明: 二维函数光子晶体比二维常规光子晶体的带隙更宽; 通过变换介质柱介电常数不同的线性函数形式可使二维函数光子晶体的带隙个数、位置和宽度均发生变化, 从而实现对二维函数光子晶体带隙的调节.

| Abstract: | The effects of different linear functional forms of dielectric column dielectric constant of two-dimensional functional photonic crystals on transverse electric (TE) wave and transverse magnetic (TM) wave band structures were studied by using plane wave expansion method. The results of numerical calculation show that the band gaps of two-dimensional functional photonic crystals are wider than that of two-dimensional conventional photonic crystals. By changing the different functional forms of dielectric column dielectric constant, the number, position and width of band gaps of the two-dimensional functional photonic crystals can be changed, so as to adjust the band gap of two-dimensional functional photonic crystals. |
