摘　　要：无序体系中电子局域化的概念是由安德森(P.W.Anderson)在1958年提出的。从那时起安德森局域化就成为物理学中的热门研究问题,而今在新材料等领域着有广泛的运用。本文通过搭建简单的光路系统,测量了无序聚苯乙烯小球体系相干背散射光强分布、反射透射光强变化关系,初步分析了该体系相干背散射特性与安德森局域化的关系,探讨了该体系中通过相干背散射现象研究光子的安德森局域化现象和规律的可能性。The concept of electronic localization in a disordered system was proposed by P.W.Anderson in 1958.Since then,Anderson’s localization has become a hot research issue in physics,nowerdays it is widely used in new materials and other fields.The relationship between the coherent backscattered light intensity distribution and the reflected transmitted light intensity of the disordered polystyrene sphere system is measured by constructing a simple optical system.The relationship between the coherent backscattering characteristics of the system and the localization of Anderson is analyzed.In this system,the phenomenon of Anderson localization and the possibility of regularity of photons are studied by the phenomenon of coherent backscattering.
