Study on the FDTD simulation of the 1-D photonics crystal

Qi Song

Abstract

The principle of finite difference time domain (FDTD) was presented,and analysis of electromagnetic field in 1D photonics crystal(PC) was performed.Based on the study of transmittance of 1D PC,influence of different periods and dielectric constant ratios on the photonics band gap were discussed.The defect state was formed by introducing the defect layer into period structure.
