MWSW02 - Theory of wave scattering in complex and random media

This talk is intended to be an introduction to the subject matter of wave multiple scattering, emergence of effective medium and the derivation of the relevant basic equations. By approaching the condition of effective medium from the point of view of the ensemble-averaged Green function, it is shown that a numerical approach to the intermediate frequency regime is possible. The latter is illustrated by an example with both theory and experimental results on an acoustically strongly scattering medium. The talk ends with a physical interpretation of the results. The materials of this talk are from sections of the monograph “Introduction to wave scattering, localization and mesoscopic phenomena. Springer Science 2006”.
