Rayleigh centennial

Applied Optics, 1975
This brief sketch of the contributions of the fourth Baron Rayleigh is intended to supplement the biographical material contained in the October 1964 issue of Applied Optics.

Coherent Rayleigh Scattering

Physical Review Letters, 2000
The spectrum of coherent scattering induced by electrostriction in gases has been analyzed in the previously unexplored, free-molecule limit by solving Boltzmann's equation with a periodic force due to the optical fields. Calculated and measured spectra of several gases at rarefied conditions are nearly Gaussian with widths approximately 10% wider than

Lumped Rayleigh reflectors

Optics Letters, 2017
Distributed acoustic sensing (DAS) via optical fibers makes use of Rayleigh backscattering for the detection of acoustic waves that interact with the fiber along its entire length. The random nature of Rayleigh backscattering leads to nonuniform performance along the fiber and, occasionally, to complete signal fading.

Rayleigh scattering

Applied Optics, 1981
We all know that blue skies and red sunsets are due to the “Rayleigh scattering” of sunlight. But beyond that, Rayleigh scattering means different things to different scientists.

Superfluid Rayleigh criterion

Physical Review B, 1995
The stability of the flow of superfluid helium II between two corotating cylinders is investigated. The result is compared with the corresponding classical flow of helium I. The validity of Rayleigh`s stability criterion and the relation between a superfluid and a classical inviscid fluid are discussed.

Rayleigh–Bénard and Rayleigh–Taylor Instabilities

2014
The stability of a near-critical fluid is studied in the Rayleigh–Benard configuration: the fluid is heated from below or presents itself as a layer of a heavier fluid is on top a lighter one. The Rayleigh–Benard instability is first addressed showing a double Rayleigh–Benard situation thanks to the presence of the piston effect.
