We interpret cooperative scattering by a collection of cold atoms as a multiple-scattering process. Starting from microscopic equations describing the response of N atoms to a probe light beam, we represent the total scattered field as an infinite series of multiple-scattering events. As an application of the method, we obtain analytical expressions of the coherent intensity in the double-scatt...

Two mechanisms important for the interpretation of radar observations of the atmosphere, are: coherent scattering from refractive index fluctuations of the clear-air and incoherent scattering from particles. These scattering mechanisms have very different wavelength dependencies and their contributions to the radar return can be separated by using two radars with different wavelengths. A differ...

We present a QCD calculation of the coherent multiple scattering effect on single hadron production in semi-inclusive lepton-nucleus deep inelastic scattering (DIS). We show that the destructive interference of coherent multiple scattering leads to suppression in hadron productions. The suppression is similar to the expectations of energy loss calculations. We compare our calculation with exper...

A microwave scattering formulation is presented for grassland and other short vegetation canopies. The fact that the constituent elements of these targets can be as large as the vegetation layer make this formulation problematic. For example, a grass element may extend from the soil surface to the top of the canopy, and thus the upper portion of the element can be illuminated with far greater e...

1 Introduction Coherent optical techniques contrast with those based on incoherent processes such as laser induced fluorescence or spontaneous Raman scattering by emitting a signal in a laser-like beam of radiation. For combustion diagnostics this presents obvious advantages for efficient collection of the signal and discrimination against background noise from scattered light or luminescence f...
