三维随机介质中波的横向约束
Transverse confinement of waves in 3D random media
摘要：
本文研究了安德森局域区中紧聚焦光束通过厚的三维无序介质平板的传输。我们表明，透射光束的横向轮廓表现出明确的签名安德森局域化，其均方宽度提供了一个直接的本地化长度的测量。对于短入射脉冲，宽度与吸收无关。
英文摘要：
We study the transmission of a tightly focused beam through a thick slab of 3D disordered medium in the Anderson localized regime. We show that the transverse profile of the transmitted beam exhibits clear signatures of Anderson localization and that its mean square width provides a direct measure of the localization length. For a short incident pulse, the width is independent of absorption.
