(2+1)维光的相干多重光的散射

Coherent multiple scattering of light in (2+1) dimensions

Nicolas Cherroret

摘要:

本文在不对波动方程作任何傍轴近似和不充分考虑光的矢量特性的情况下,建立了光在沿两个方向空间无序而沿第三个方向空间均匀的介质中的多次散射理论。有了这种形式主义,我们计算的光束的横向动量的分布,因为它沿着光轴的演变,并揭示了一个现象没有捕获的傍轴方程:从标量到矢量政权的交叉,可见的相干后向散射峰偏振变得随机。

英文摘要:

We formulate a multiple scattering theory of light in media spatially disordered along two directions and homogeneous along the third one, without making any paraxial approximation on the wave equation and fully treating the vector character of light. With this formalism, we calculate the distribution of transverse momenta of a beam as it evolves along the optical axis, and unveil a phenomenon not captured by the paraxial equation: a cross-over from a scalar to a vector regime, visible in the coherent backscattering peak as polarization gets randomized.
