Inverse scattering transform for wave-wave scattering

Physical Review A, 1975
Abstract : An inverse scattering transform method is outlined for the resonant interaction of two plane waves (an incident wave of amplitude (A sub 1) and radian frequency (Omega sub 1) and a scattered wave of amplitude (A sub 2) and frequency (Omega sub 2) with a medium which can propagate a classical scattering waves (of amplutude Y and frequency ...

Wave scattering in waveguides

Journal of Mathematical Physics, 2003
The scattering of scalar waves by objects located inside a waveguide or a cavity is discussed using the method of pseudopotentials. Pseudopotentials were introduced to simulate short-range potentials in quantum mechanics and proved useful in many-body problems and in problems involving multicentered potentials.

Multiple Scattering of Waves

Journal of Mathematical Physics, 1961
Multiple scattering effects due to a random array of obstacles are considered. Employing a ``configurational averaging'' procedure, a criterion is obtained for the validity of approximate integral equations describing the various field quantities of interest.

Chaotic Wave Scattering

2010
We give an overview of wave scattering in complex geometries, where the corresponding rays are typically chaotic. In the high-frequency regime, a number of universal (geometry-independent) properties that are described by random matrix theory emerge. Asymptotic methods based on the underlaying rays explain this universality and are able to go beyond it

Transmittance for wave-packet scattering

Physical Review A, 1992
Different expressions for the transmittance in wave-packet scattering in one dimension are examined. Special attention is paid to the difficulties when the initial packet ρ(0) has negative momentum components. A general formula is provided for this case, and the domain of applicability of a simple approximate expression is indicated.

Inverse scattering with diffusing waves

Journal of the Optical Society of America A, 2001
We consider the problem of imaging the optical properties of a highly scattering medium probed by diffuse light. An analytic solution to this problem is derived from the singular value decomposition of the forward-scattering operator, which leads to explicit inversion formulas for the inverse scattering problem with diffusing waves.
