Topic:
Kinetic Models for
Wave Propagation in Random Media
Abstract:
In recent years,
Wigner transforms have successfully been used to
analyze the
asymptotic behavior of high frequency wave
solutions. Wigner
transforms characterize micro-locally (i.e., in the
phase space) the
oscillatory behavior of functions with a prescribed
physical scale. As
such, they may be seen as extensions of geometric
optics
constructions in the semiclassical regime. Wigner transforms
have also been used
to derive kinetic models for the radiative
transfer of the
energy density of waves propagating in random media.
In this talk, I
will review several of these models and present what
is known about them
mathematically. I will focus on the application of
such kinetic models
to the understanding of the enhanced refocusing
properties of time
reversed waves propagating in heterogeneous media.
