共振光在静止点散射系综平面上的反射：量子微观方法
Reflection of resonant light from a plane surface of an ensemble of motionless point scatters: Quantum microscopic approach
摘要：
基于先前在[JETP 112，246（2011）]中开发的一般理论结果，我们分析了准共振光从静止点散射的密集和无序系综的平面表面的反射。散射光的角度分布计算为s和p偏振的探测辐射。计算散射光的相干和非相干（漫射）分量之间的比率。我们分析了位于不同距离的表面散射的贡献，并确定在此背景下负责反射光束生成的表面层的厚度。讨论了表面附近偶极-偶极相互作用的不均匀性，研究了总反射光功率与入射角的关系，并将微观方法的结果与菲涅耳反射理论的预测进行了比较。对不同密度的散射体和不同频率的探测辐射进行了计算。
英文摘要：
On the basis of general theoretical results developed previously in [JETP 112, 246 (2011)], we analyze the reflection of quasiresonant light from a plane surface of dense and disordered ensemble of motionless point scatters. Angle distribution of the scattered light is calculated both for s and p polarizations of the probe radiation. The ratio between coherent and incoherent (diffuse) components of scattered light is calculated. We analyze the contributions of scatters located at different distances from the surface and determine on this background the thickness of surface layer responsible for reflected beam generation. The inhomogeneity of dipole-dipole interaction near the surface is discussed.We study also dependence of total reflected light power on the incidence angle and compare the results of the microscopic approach with predictions of the Fresnel reflection theory. The calculations are performed for different densities of scatters and different frequencies of a probe radiation.
