摘　　要：光子晶体具有不同介电常数的物质在空间周期性排列而成的人工微结构,是一种能承载电磁波传播的新型光学材料,具有光子带隙、抑制自发辐射、光子局域、偏振特性等性能。利用传输矩阵方法导出光波在一维光子晶体中传播的反射系数和透射系数,分析了不同参数对应的光子带隙,发现介质折射率对光子带隙有着明显的影响。Photonic crystal is artificial microstructures with different dielectric constant of the material periodic arrangement in the space,a novel optical material bearing the propagation of electromagnetic wave,and it has a photonic band gap,the suppression of spontaneous radiation,photon localization,polarization properties.The reflection and transmission coefficients are derived using the transfer matrix method of optical wave propagation in one-dimensional photonic crystals,finding out that the refractive index has obvious influence to zhe the photonic band gap.
