Abstract

The principle of finite difference time domain(FDTD)was presented,a one-dimensional model consisting of ZnO and MgF2 is proposed,and analysis of electromagnetic field in 1D photonic crystal(PC)was performed.Based on the study of transmittance of 1D PC,influence of different Periods different thickness and different thickness ratios on the photonics band gap were discussed.The defect state was formed by introducing the defect layer into period structure.
