几种三维光子晶体模型的等效光学分析

here are three typical structures of photonic crystals, namely the hexagonal close-packed structure, face-centered cubic structure and body-centered cubic structure. In this paper, three-dimensional photonic crystals were simplified into one-dimensional photonic crystals by equal volume method. The equivalent numerical result was calculated by transfer matrix method, and then the spectral reflectance curves of different layer, size and angle were given with the software Matlab. The photonic band width was determined by nanoparticle film layer. With the increase of particle size, the photonic crystal band gap move to long wave. The color of the photonic crystal changes with incident angle. Because those are kept with the actual performance of three dimensional photonic crystal, the method is practical and effective.
