Height scattering indicatrices and the earth's atmosphere scattering coefficient

SPIE Proceedings, 1997
Observation material of 1993 - 1995 seasons is reduced and optical characteristics of upper atmosphere of the Earth are obtained, and namely: height indicatrices of terrestrial atmosphere scattering and volume coefficient of scattering. For wavelengths 754 nm and 585 nm indicatrices of scattering are obtained for height 10, 20, . .

Specular Scattering With Effective Reflection Coefficient

International Geoscience and Remote Sensing Symposium, 'Remote Sensing: Moving Toward the 21st Century'., 2005
This study deals with the relationship between backscattering coefficient and wind speed for microwave frequencies at normal incidence angle. The quasi specular scattering theory for rough dielectric surface has been applied with effective reflection coefficient and refined sea spectrum.

A Calculation of Mass Scattering Coefficients

Physical Review, 1934
By means of graphical integration, the mass scattering coefficients of the substances carbon, aluminum, iron, tin and gold have been calculated over the wave-length range $\ensuremath{\lambda}=0.4\mathrm{A} \mathrm{to} 1.1\mathrm{A}$. The results show: (1) the mass coefficients obtained agree reasonably well with those obtained experimentally by Coade,

Light scattering coefficients for textured SnO

Solar Energy Materials and Solar Cells, 2001
Abstract Transparent electrodes that are used in amorphous silicon solar cells are textured to provide light scattering. We studied the light scattering behavior in transmission and reflection and found that in order to describe the measured spectra thickness variations of 50–60 nm over several micrometers have to be assumed.

Lidar effective multiple-scattering coefficients in cirrus clouds

Applied Optics, 1997
We delimit a regime, valid for most ground-based lidar probings of cirrus clouds, in which the field-of-view dependence of multiple scattering reaches a plateau. In this regime and assuming the phase function to be constant around pi, we formally demonstrate Platt's modification of the single-scattering lidar equation, with a parameter eta(P ...

Exponential decay of scattering coefficients

2016
We study an aspect of the following general question: which properties of a signal can be characterized by its scattering transform? We show that the energy contained in high order scattering coefficients is upper bounded by the energy contained in the high frequencies of the signal.

Estimation of Correlation Coefficients from Scatter Diagrams

Journal of Applied Physics, 1954
Theoretical relations between statistical scatter diagrams of two random variables and their joint probability density functions are used to derive a simple method of estimating correlation coefficients. The cases considered are those of variables with Gaussian and Rayleigh distributions.

Reflection coefficients of large active scatterers

Journal of Applied Physics, 1985
The reflection from large absorbing scatterers having a complex refractive index m=n1−iκ (κ>0), is determined by the Fresnel reflection coefficients. Lasing materials with inverted population or having a complex refractive index m=n1+iκ ‘‘reflect’’ the incident light with different coefficients, since internal reflections must be taken into ...

Absorption, scattering, and diffusion coefficients: Overview.

The Journal of the Acoustical Society of America, 2010
Acoustical design and computer modeling rely on the availability, accuracy, and use of coefficients which characterize how boundary surfaces affect incident sound. At this time three coefficients have been developed to characterize how incident sound is modified by absorptive and scattering surfaces.

The Wear Coefficient—Magnitude, Scatter, Uses

Journal of Lubrication Technology, 1981
One of the key factors in the analysis of a wear problem is the computation of the wear coefficient for a comparison with the value to be anticipated for this application. Typical values of adhesive wear coefficients for a variety of materials and lubricants are presented, and the values compared with those arising in the wear modes of abrasion ...
