Multiple Scattering Of Light In Inhomogeneous Media And Applications
Light scattering-based techniques are being developed for non-invasive diagnostics of inhomogeneous media in various fields, such as medicine, biology, and material characterization. However, as most media of interest are highly scattering and have a complex structure, it is difficult to obtain a …

Nanostructures and alloys : multiple scattering and nonlinearities in phonon transport
… and dielectrics. Effective field theories and scattering theory have been combined to model alloys and systems with embedded nanostructures. The simplest of such effective field theories, the Virtual Crystal approximation, fails to capture short-length scale information due to the inherent …

Multiple scattering of microwaves from soil surface and vegetation canopies
A multiple scattering radiative transfer model is developed for use in global retrieval algorithms of microwave geophysical parameters. This attempts to both improve soil moisture and vegetation attenuation and scattering parameter retrievals under moderate to dense canopy covers and capture the …

Multiple scattering of electromagnetic waves by distributions of particles with applications to radio wave propagation through precipitation
The Twersky procedure is used to derive the vector Foldy-LaxTwersky integral equation (Dyson equation) for the coherent field in a random distribution of particles. The above equation is applied to ice depolarization and rain attenuation and depolarization. Twersky's procedure is then extended in …
