| Abstract: | The photonic band of kinds of quasi fractal photonic crystal is calculated by finite difference time domain method. The results show that there are multi stopband characteristics with the quasi fractal photonic crystal.As we treat these photonic band gaps as one photonic band gap with several conduction bands in it, the width and center frequency of the photonic band gap, and also the center frequency of the conduction bands in the photonic band gap vary with changing the structure of the unit cell of the quasi fractal photonic crystal. |
| Keywords: | Photonic crystal Photonic band gap Fractal Filter |
