| Abstract: | A systematic theoretical investigation was undertaken in order to model the band gap structures of two-dimensional periodic dielectric materials with a finite-difference time-domain method. By altering the ratio of dielectric electric permittivity and being different defect, we got numerical result correspondingly and analysed it. These may give instruction in designing photonic crystal devices. |
