We study the diffusion of monochromatic classical waves in a disordered acoustic medium by scattering theory. In order to avoid artifacts associated with mathematical point scatterers, we model the randomness by small but finite insertions. We derive expressions for the configuration-averaged energy flux, energy density, and intensity for one-, two-, and three-dimensional (3D) systems with an embedded monochromatic source using the ladder approximation to the Bethe-Salpeter equation. We study…

Specific features of optical diffusion in nematic liquid crystals

Methods of computer simulation are used to study multiple light scattering in the ordered phase of a nematic liquid crystal. The development of the diffusion regime is studied in detail. It is



Extracting the Green function from diffuse, equipartitioned waves.

A ballistic pulse launched in a strongly scattering random medium becomes diffusive after a few mean-free times and the two-point, two-time correlation of the wave-field should equal the sum of the advanced and retarded Green functions associated with the average medium.

Diffusing-Light Spectroscopies Beyond the Diffusion Limit: The Role of Ballistic Transport and Anisotropic Scattering

Diffuse transmission and diffusing-wave spectroscopy (DWS) can be used to probe the structure and dynamics of opaque materials such as colloids, foams, and sand. A crucial step is to model photon

Breakdown of wave diffusion in 2D due to loops.

It is shown that the diffusion equation underestimates the intensity of multiply scattered waves and a theory is presented to quantify this discrepancy based on counting all possible scattering paths between point scatterers.

Impact of weak localization in the time domain.

We find a renormalized "time-dependent diffusion coefficient," D(t), for pulsed excitation of a nominally diffusive sample by solving the Bethe-Salpeter equation with recurrent scattering. We observe

Multiple scattering of classical waves: microscopy, mesoscopy, and diffusion

important corrections are presented. These corrections are calculated with the radiative transfer or Schwarzschild-Milne equation, which describes intensity transport at the ‘‘mesoscopic’’ level and

Localization of classical waves in weakly scattering two-dimensional media with anisotropic disorder.

It is shown that in the long-wavelength limit the radiation is always localized, and the localization length is independent of the direction of propagation, the latter in contrast to the predictions based on an anisotropic tight-binding model.

Wave transport through thin slabs of random media with internal reflection: Ballistic to diffusive transition.

The static and dynamic properties of wave transport through thin slabs of random media in the presence of internal reflection are investigated by performing first-principles calculations and an abrupt transition from ballistic to diffusive behavior is found.

Observation of Anomalous Transport of Strongly Multiple Scattered Light in Thin Disordered Slabs

We present results of experiments on the transport of light through thin random media. Total transmission and time-resolved propagation measurements were performed using strongly scattering samples

Quasi-two-dimensional transfer of elastic waves.

A time-dependent, quasi-two-dimensional radiative transfer equation is derived that describes the coupling of the eigenmodes of the layer (surface Rayleigh waves, shear horizontal waves, and Lamb waves) and facilitates a study of coherent backscattering near the plate surface for different sources and for different detection configurations.

Relation between time reversal focusing and coherent backscattering in multiple scattering media: a diagrammatic approach.

This paper revisits one-channel time reversal experiments through multiple scattering media in the framework of the multiple scattering theory and shows that when the initial source and the time reversal point are at the same location, the time-reversed amplitude is twice higher.
