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

Rayleigh–Bénard and Rayleigh–Taylor Instabilities
2014The 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.

Soft Matter, 2019
Soft gel drops exhibit shape oscillations which obey a dispersion relationship that depends upon elastocapillary and compressibility effects, thus extending the classical analysis for the Rayleigh drop to include elasticity.

Considerations to Rayleigh’s hypothesis
Optics Communications, 2009Abstract In 1907 Lord Rayleigh published a paper on the dynamic theory of gratings. In this paper he presented a rigorous approach for solving plane wave scattering on periodic surfaces. Moreover he derived explicit expressions for a perfectly conducting sinusoidal surface, and for perpendicular incidence of the electromagnetic plane wave. This paper

A Note on the Rayleigh Polynomials
SIAM Journal on Mathematical Analysis, 1978Some formulae and representations of the nth order Rayleigh functions, $\sigma _n $, and their associated polynomials, $\phi _n $, are used to determine polynomials which dominate, or are dominated by, $\phi _n $, and to discuss improved lower bounds for their real roots. In the process the ties between $\phi _n $, and the Catalan numbers are enhanced.

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.

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.

Discrete Rayleigh Distribution
IEEE Transactions on Reliability, 2004Using a general approach for discretization of continuous life distributions in the univariate & bivariate situations, we have proposed a discrete Rayleigh distribution. This distribution has been examined in detail with respect to two measures of failure rate.

On Rayleigh's Problem in Magnetohydrodynamics
The Physics of Fluids, 1960A comparison is made of three flow fields that may be described as Rayleigh's problem in magnetohydrodynamics and that differ only in the state of motion of the magnetic field. Deviation of approximate expressions for the velocity from the more exact relations are also presented when the ratio of the viscous and magnetic Reynolds numbers is unity.
