Paper Abstract

In this paper, we used FDTD Solutions software to simulate the reflectance of two-dimensional photonic crystal by changing duty ratio from 40% to 70%. The different models, which are referred by Stavenga, Southwell and Grann et al, were used for obtaining the equivalent refractive index. And then the simulations of double layer dielectric structure designed in FDTD Solutions was used for getting the reflectance curves by importing the data of the equivalent refractive index. After comparing these curves we could obtain that the accuracy of different models are related to the ratio of the period(P) and wavelength(λ). Thus the equivalent refractive theory has its most applicable models of micro structure in different period scales. The imprecise quantitative explaining of micro structures’ antireflection by using equivalent refractive theory models was solved in this paper, which has important significance in many areas.
