Transport of quantum noise through random media [PDF]
, 2004 We present an experimental study of the propagation of quantum noise in a multiple scattering random medium. Both static and dynamic scattering measurements are performed: the total transmission of noise is related to the mean free path for scattering ...

Effects of localization and amplification on distribution of intensity transmitted through random media [PDF]
, 2004 We numerically study the statistical distribution of intensity transmitted through quasi-one dimensional random media by varying the dimensionless conductance $g$ and the amount of absorption or gain.

Surface Parameters Retrieval from Fully Bistatic Radar Scattering Data
Remote Sensing, 2019 Fully bistatic radar scattering from rough surfaces is of vital importance in terrain remote sensing, but results in bulky data volume. The scattering is dependent on physical parameters of the media and is controlled by the radar observation geometry ...

Field and intensity correlations in amplifying random media [PDF]
, 2004 We study local and nonlocal correlations of light transmitted through active random media. The conventional approach results in divergence of ensemble averaged correlation functions due to existence of lasing realizations.

Speed of light in random media [PDF]
Physical Review B, 1992 We give a microscopic derivation of the speed of light relevant for energy transport in media containing randomly distributed scatterers. A comparison is made with the concept of ``mass enhancement'' in electron transport theory. The consequences for the Thouless criterion for strong localization are discussed.

Stiff directed lines in random media
, 2013 We investigate the localization of stiff directed lines with bending energy by a short-range random potential. We apply perturbative arguments, Flory scaling arguments, a variational replica calculation, and functional renormalization to show that a ...
