Diffusive light transport in semitransparent media

L Pattelli, G Mazzamuto, DS Wiersma, C Toninelli - Physical Review A, 2016 - APS
It is common knowledge that diffusion theory cannot describe light propagation in
semitransparent media, ie, media with a low optical thickness. However, even in an optically …

Universal structure of transmission eigenchannels inside opaque media

M Davy, Z Shi, J Park, C Tian, AZ Genack - Nature communications, 2015 - nature.com
As the desire to explore opaque materials is ordinarily frustrated by multiple scattering of
waves, attention has focused on the transmission matrix of the wave field. This matrix gives …

Optical diffusion of continuous-wave, pulsed, and density waves in scattering media and comparisons with radiative transfer

AD Kim, A Ishimaru - Applied optics, 1998 - opg.optica.org
We discuss several outstanding theoretical problems in optical diffusion in random media.
Specifically, we discuss which of several diffusion theories most closely approximates exact …

Reduced transport velocity of multiply scattered light due to resonant scattering
