Correlations of heterogeneous wave fields propagating in homogeneous media

  title={Correlations of heterogeneous wave fields propagating in homogeneous media},
  author={Guillaume Bal and Olivier Pinaud},
The paper concerns the analysis of the correlations of wave fields propagating in heterogeneous media. We show that selected field-field correlations asymptotically propagate in non-scattering media, i.e., propagate as if the underlying medium was homogeneous. Such correlations are therefore good candidates for imaging strategies in heterogeneous media based on back-propagations in a homogeneous medium. keywords: inverse problem, imaging, correlations, radiative transfer, random media.

We consider the imaging of objects buried in unknown heterogeneous media. The medium is probed by using classical (e.g. acoustic or electromagnetic) waves. When heterogeneities in the medium become
Kinetic Models for Imaging in Random Media
This work quantifies the influence of small objects on (i) the energy density measured at an array of detectors and (ii) the correlation between the wave field measured in the absence of the object and theWave field measuredIn the presence of the objects.
Accuracy of transport models for waves in random media
Communication through a diffusive medium: coherence and capacity
The theory of electromagnetic wave propagation in diffusive media is combined with information theory to show how interference affects the information transmission rate between antenna arrays.
Wave propagation and scattering in random media
This IEEE Classic Reissue presents a unified introduction to the fundamental theories and applications of wave propagation and scattering in random media and is expressly designed for engineers and scientists who have an interest in optical, microwave, or acoustic wave propagate and scattering.
Experimental validation of a transport-based imaging method in highly scattering environments
We demonstrate the effectiveness of a transport-based reconstruction method for imaging in highly scattering environments. Experimentally measured wave energy data in the micro-wave regime are used
Stability of time reversed waves in changing media
We analyze the refocusing properties of time reversed waves that propagate in two different media during the forward and backward stages of a time-reversal experiment. We consider two regimes of
Electromagnetic Time-Reversal Imaging in Changing Media : Experiment and Analysis
An experimental study is performed on electromagnetic time reversal in highly scattering environments, with a particular focus on performance when environmental conditions change. In particular, we
