| 摘 要： | 应用多重散射方法计算了二维介质柱构成的非晶光子材料的缺陷态。在非晶光子材料中抽掉不同位置的圆柱会产生频率不同的缺陷模，但缺陷模的能量都是非常局域的，能量基本上集中在以缺陷波长1／3为半径的圆内。这表明非晶光子材料中形成的缺陷模不仅具有周期性光子晶体的缺陷模的强局域化特征，同时缺陷模更富于变化。 |

| Abstract: | The defect states in two dimensional amorphous photonic materials composed of dielectric cylinders are calculated by using a multiple scattering method. The simulating results show that the frequencies of the defect states are different from each other when various cylinders are removed, meanwhile the energy of electromagnetic wave is almost localized in a circle whose radius is less than one third of the defect wavelength. These reveal that the defects of the amorphous photonic materials have the same property as the defect of a periodic photonic crystal for the case of strong energy localization, furthermore the defect modes in the amorphous photonic materials are richer than in the periodic photonic cyrstal. |
| Keywords: | amorphous photonic materials photonic crystal defect state localization length |
