Beschreibung
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.
Random Media and Boundaries presents a theory of boundary-value transport problems based on the Bethe-Salpeter equation. The topics discussed include: layer problems, a fixed scatterer imbedded in a bounded medium, construction of an optical scattering matrix for a complete system, and optical wave propagation in a turbulent medium. This book will be of interest to graduate students and researchers.
