Bai Jurong, Li Xiaoyan, Zhao Na, et al. Computations of one-dimensional photonic crystal band-gap structures using Rouard’s method[J]. 2007,(6):37-39. DOI: 10.13756/j.gtxyj.2007.06.020.
which is widely used in the thin film optics and the calculations of waveguide grating theory
is introduced into the calculations of the band-gap structures of one-dimensional photonic crystal and the causes for the generation of photonic band-gap explained in light of the multi-beam interference theory of physical optics.The relevant formulas of Rouard’s method are derived in detail and the Rouard’s method is used to calculate the reflectance spectrum of the one-dimensional photonic crystal with different structures.The results show that the Rouard’s method is effective
clear in physical concepts and concise in formaula expression.
