光相干后向散射中的能量守恒

Conservation of energy in coherent backscattering of light

摘要:

虽然能量守恒是物理学中的基本原理,但在混浊介质中波的传播领域中,相干后向散射锥的能量增强似乎违反了它的原理。在这封信中,我们提出的实验数据表明,在所有的散射角的能量削减平衡的圆锥的能量增强。而且,我们给出了一个完整的理论描述,这与这些数据很好地吻合。在本说明书中,为了加强能量守恒所需的附加项是由入射波和多次散射波之间的干涉效应引起的,这让人想起了单次散射中的光学定理。

英文摘要:

Although conservation of energy is fundamental in physics, its principles seem to be violated in the field of wave propagation in turbid media by the energy enhancement of the coherent backscattering cone. In this letter we present experimental data which show that the energy enhancement of the cone is balanced by an energy cutback at all scattering angles. Moreover, we give a complete theoretical description, which is in good agreement with these data. The additional terms needed to enforce energy conservation in this description result from an interference effect between incident and multiply scattered waves, which is reminiscent of the optical theorem in single scattering.
