Theoretical analysis of backscattering in hollow-core antiresonant fibers
APL Photonics, 2021 We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with gases,

A Fast Single-Image Dehazing Algorithm Based on Dark Channel Prior and Rayleigh Scattering
IEEE Access, 2020 The scattering of atmospheric particles significantly alters images captured under hazy weather condition. Images appear distorted, blurry and low in contrast attenuation, which extensively affects computer vision systems.

Many-electron effects on the x-ray Rayleigh scattering by highly charged He-like ions
, 2016 The Rayleigh scattering of x-rays by many-electron highly charged ions is studied theoretically. The many-electron perturbation theory, based on a rigorous quantum electrodynamics approach, is developed and implemented for the case of the elastic ...

Non‐Rayleigh Statistics of Ultrasonic Backscattered Echo from Tissues [PDF]
, 1994 The envelope of the backscattered signal from tissues can exhibit non‐Rayleigh statistics if the number density of scatterers is small or if the variations in the scattering cross sections are random. The K distribution which has been used extensively in

Decoherence due to elastic Rayleigh scattering
, 2010 We present theoretical and experimental studies of the decoherence of hyperfine ground-state superpositions due to elastic Rayleigh scattering of light off-resonant with higher lying excited states.
