    摘要:

    对含有反常色散材料和金属材料散射体无序介质的光子定域化行为进行了理论研究 .基于Mie散射理论研究发现 ,对于某些反常色散电介质球做散射体的无序介质 ,在较低浓度 (10 % )下 ,在中红外区可以实现一定的光子定域化 ,且频率位于各自的剩余射线带 .对金属散射体的无序光学介质的研究表明 ,各种金属在中红外区的各个频率点上的散射行为均极为相近 ,结果表明 ,在整个中红外区几乎不可能实现光子定域化 .

    Abstract:

    Photon localization of random media containing anomalous dispersive dielectric materials and metal scatterers, was investigated theoretically. Based on the Mie scattering theory in mid infrared region at low concentration(10%), photon localization of random media with some anomalous dispersive dielectric spheres as scatterers, was realized, and strong photon localization was appeared in reststrahelm band freqances. Investigations of random optical media with metal scatterers was finished, and discovered that scattered behaviours of different metals in mid infrared region at different freqences were very similar. The results show that it is almost impossible that photon localization in the whole mid infrared region.
