三维FDTD方法计算光子晶体薄板结构

Three Dimensional Finite Difference Time Domain Method Calculate Photonic Crystal Slab

利用三维时域有限差分方法计算了具有不同介电常数的光子晶体薄板结构,得到了这些结构的带隙的数值结果,并作了分析;这些结果对于设计光子晶体器件有着指导作用。

We used three Dimensional Finite Difference Time Domain Method (FDTD) to calculate photonic cry- stal slab with different refractive index and got the numerical result of the bandgap and analyse it, which may give instruction in designing photonic crystal devices.
