Rayleigh and hyper-Rayleigh scatterings in solution

Optics & Laser Technology, 2004
Abstract A concept of concentration gradient induced by incident radiation which describes the dependence of the Rayleigh ( I ω ) and hyper-Rayleigh ( I 2 ω ) intensities on the power as well as background concentration is proposed. In our previous paper, we have demonstrated the effect of concentration gradient on the first-, second- and third ...

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

The elastic Rayleigh drop

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, 2009
Abstract 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

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.

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.

Discrete Rayleigh Distribution

IEEE Transactions on Reliability, 2004
Using 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.

Rayleigh's Problem in Magnetohydrodynamics

The Physics of Fluids, 1959
Extension of Rayleigh's problem to magnetohydrodynamics is investigated for a perfectly conducting plate with a transversely applied magnetic field. Induced electric and magnetic fields are both included in the analysis. Results obtained show that along the plate an electromagnetic body force will act in the direction of fluid motion.
