Scattering on Stratified Media: the Micro-local Properties of the Scattering Matrix and Recovering Asymptotics of Perturbations
نویسنده
چکیده
The fixed energy scattering matrix is defined on a perturbed stratified medium, and for a class of perturbations, its main part is shown to be a Fourier integral operator on the sphere at infinity. This is facilitated by developing a refined limiting absorption principle. The symbol of the scattering matrix is shown to determine the asymptotics of a large class of perturbations.

Recovering Asymptotics of Metrics from Fixed Energy Scattering Data
The problem of recovering the asymptotics of a short range perturbation of the Euclidean metric on R n from xed energy scattering data is studied. It is shown that if two such metrics, g 1 ; g 2 ; have scattering data at some xed energy which are equal up to smoothing, then there exists a diieomorphism`` xing innnity' such that g 1 g 2 is rapidly decreasing. Given the scattering matrix at two e...
متن کاملTowards Measurement of Polarization Properties of Skin using the Ellipsometry Technique
Introduction: The human skin is an active medium from the optical point of view. Therefore, the diagnostic and therapeutic techniques employing light are increasing. Current optical techniques are based on the measurement of the intensity of reflected absorbed or backscattered light from or within skin. Studies have shown that biological tissues, and in particular skin, demonstrate polarization...
متن کاملA STUDY OF GAMMA RAY EXPOSURE BUILDUP FACTORS IN STRATIFIED SHIELDS FOR POINT ISOTROPIC SOURCES, INCLUDING THE EFFECTS OF INCOHERENT AND COHERENT SCATTERING
The effects of including incoherent (bound-electron) and coherent (Rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (E?) range of 40 keV to 3 MeV. Incoherent scattering decreases the values of these factors in both layers up to E? ~ 200 keV and the effect i...
