Random Media and Boundaries

For a system consisting of a random medium with rough
boundaries, the         governing (Bethe-Salpeter) equation for
boundary-value transport problems   can be written in a form
such that the medium and the boundaries are treatedon an
equal footing. This enables several expressions for the
solution   to be obtained by interchanging the roles of the
medium and the boundaries, thus allowing the most convenient
one to be selected according to the         specific situation and
the information required. This book presents a         unified
theory based on the Bethe-Salpeter equation with                              particular
attention being paid to: boundary-value problems                        of
transport, layer problems, a fixed scatterer imbedded in a
bounded   random medium, construction of an optical scattering
matrix for a complete   system, and optical wave propagation
in a turbulent medium. The last topic   is treated in terms of
first moment equations combined with the cluster      expansion
and, second, the two-scale method based on the                              Lagrange
variational principle.
