Frequency width of open channels in multiple scattering media

Multiple scattering in evolving media

techniques that are used, for example, in radar and in seismic exploration. If one knows the arrival time of a singly scattered wave, along with its velocity and direction of propagation, one can determine the location of the scatterer. For multiply scattered waves it is more difficult to determine the locations of the scatterers because the waves propagate over many possible scattering traject...

An analysis of electromagnetic scattering from finite-width strips

Multiple scattering of light in superdiffusive media.

Light transport in superdiffusive media of finite size is studied theoretically. The intensity Green's function for a slab geometry is found by discretizing the fractional diffusion equation and employing the eigenfunction expansion method. Truncated step length distributions and complex boundary conditions are considered. The profile of a coherent backscattering cone is calculated in the super...

Coherent multiple scattering in disordered media

These notes contain a rapid overview of the methods and results obtained in the field of propagation of waves in disordered media. The case of Schrödinger and Helmholtz equations are considered that describe respectively electrons in metals and scalar electromagnetic waves. The assumptions on the nature of disorder are discussed and perturbation methods in the weak disorder limit are presented....

Fast Approximation of Multiple Scattering in Inhomogeneous Participating Media

This paper presents a fast approximation for the solution of the radiative transfer equation in inhomogeneous participating media. This scheme traces rays from the point light creating spherical wavefronts. While we march on a particular ray, we assume that other rays find similar material properties, which allows the solution of the diffusion equation for this ray. The proposed approximation o...
