Wave propagation and scattering in random media and rough surfaces Abstract: The author presents a comprehensive review highlighting historical as well as new developments in the area of random media. Both discrete and continuous media are considered as well as rough surfaces. The author discusses wave propagation in turbulence and in a random continuum where the refractive index is a random function of space and time. Examples are optical propagation in the atmosphere, microwaves in the troposphere, ionosphere, planetary atmosphere, and solar wind, and acoustic scattering in ocean turbulence.
We present a microscopic theory of the problem of finding the properties of a particle interacting with potentials located at random sites. The sites are governed by a general probability distribution. Neglect of the fluctuations yields the quasicrystalline approximation. With the contribution of the collective fluctuations, this yields results for A that are accurate to order t 4. Download to read the full article text. Foldy, Phys. Lax, Rev.
Directions in Electromagnetic Wave Modeling pp Cite as. This paper first presents the state of the art in the modeling of waves in random media including waves in turbulence, waves in discrete scatterers, and rough surface scattering. Secondly, we emphasize the need for interplay among analytical, numerical, and experimental investigations. Weak localization, coherent backscattering, and enhanced backscattering from rough surfaces are used as examples of these interactive investigations that are essential in constructing new analytical models and in uncovering underlying physical processes. Future directions in this field include basic theoretical studies on waves in dense media, disordered media, and nonlinear and inverse problems as well as applications in remote sensing, surface physics, geosciences, biomedical sciences, communications, and imaging.

In this work, we summarize the existing theoretical methods based on statistical and quanty theory and give some non-standard mathematical approaches based on such theories to explain the principal scalar and vector electrodynamic problems for future applications to acoustic, radio and optical wave propagation in homogeneous, isotropic, anisotropic and inhomogeneous media. We show of how the statistical description of wave equations can be evaluated based on quantum field theory with presentation of Feynman's diagrams by a limited-to-zero finite set of expanded Green functions according to perturbation theory for single, double, triple, etc, scattering phenomenon.
Нет, сэр. Какой номер вы набираете? - Сеньор Ролдан не потерпит сегодня больше никаких трюков. - 34-62-10, - ответили на другом конце провода. Ролдан нахмурился. Голос показался ему отдаленно знакомым. Он попытался определить акцент - может быть, Бургос.
