论文摘要
有效的培养基理论用于对一个维损耗的介电Quaternary光子晶体作为同质平板进行建模。原始晶体的晶胞与层序列ACBCA对称。在有效折射率指数中，分支频率奇点的行为被研究为分层结构变化中的参数。由多个光子晶体组成的异质结构还以有效的培养基理论进行建模。结果表明，这种结构的有效折射率具有正常分散区域，这些区域与代表光子带隙的异常分散总体分散区域内的局部界面状态相对应。
Effective medium theory is used to model a one dimensional lossy dielectric quaternary photonic crystal as a homogeneous slab. The unit cell of the original crystal is inversion symmetric with layer sequence ACBCA. The behavior of the branch frequency singularities in the effective refractive index is investigated as parameters in the layered structure change. A heterostructure composed of multiple photonic crystals is also modeled with effective medium theory. It is shown that the effective refractive index of such a structure possesses regions of normal dispersion that correspond to localized interface states within the overall regions of anomalous dispersion representing the photonic band gap.
