光子晶体的理论与实验研究

光子晶体是一种介电常数呈周期性分布的介质材料,周期为光波长量级。在光子晶体材料中存在着特殊的频带,在这些频带中光波被禁止传播。研究光子晶体的理论有等效折射率模型、平面波法、传输矩阵法、有限时域差分法及多极法等。制备光子晶体的技术有层层叠加技术、打孔法、微机械技术、胶体晶体法、反蛋白石法、立体平板刻蚀技术等。

Study on Photonic Crystals in Theory and Experiment

Photonic crystals are materials with periodicity of dielectric structures,which can create a range of forbidden frequencies called photonic band-gap.Photons with energies lying in the band-gap cannot propagate through the medium.We study photonic crystals by effective-index model,the finite-difference time-domain(FDTD) method,plane wave method,transfer matrix method and the multi polar method in theory.Now,we can prepared photonic crystals in experiment by layer-by-layer deposition,fabrication method,micro ...
