reflection coefficient [PDF]

, 2011
This figure shows the magnitude of the reflection coefficient, also known in the literature as the Fresnel coefficient, in terms of the angle of incidence. This representation corresponds to a wave propagating in free space an impinging onto a reflection

Some remarks about reflection coefficient.

Archivio di fisiologia, 1973
Biological membranes selectivity for solutes is measured by the reflection coefficient σ, defined as σ = (ΔP/Δπ)Jv=0 where ΔP is the hydrostatic pressure difference required to zero the volumetric flow Jv driven by an osmotic pressure difference Δπ of the considered solute.

On the geometric sequences of reflection coefficients

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990
It is shown that a decaying geometric sequence of reflection coefficients corresponds to a predictor polynomial that has all of its roots on a circle centered at the origin of the complex z plane. It is shown that the radius of this circle is equal to the magnitude of the ratio of any two consecutive terms in the geometric sequence. >

Subsets of reflection coefficients

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Subset models of autoregressive reflection coefficients have a number of non-zero reflections in the subset while the other reflections are zero. Speech analysis and seismic exploration are areas of applications where true subset processes may be found.

Invariants of the Reflection Coefficient

Optics and Spectroscopy, 2020
The reflection coefficient of a plane monochromatic wave from a three-layer structure is analyzed in detail in the case in which the wave is linearly polarized in the plane of incidence. The inverse ellipsometry problem for a three-layer structure is solved.

A reflection coefficient bridge

IEEE Transactions on Instrumentation and Measurement, 1987
The design of an unbalanced Wheatstone bridge is presented. The bridge measures the reflection coefficient of unknown impedances relative to an arbitrary reference level. A experimental unit was designed for a 25-Ω reference level. It measured high isolation with a 25-Ω load; the magnitude of the reflection coefficient with a short-circuit load ...

The Reflection Coefficient of Mercury

Journal of Applied Physics, 1938
Two new methods for measuring the reflection coefficient of mercury atoms from a mercury surface are described. In the first, a micromanometer gives both the change in pressure on the surface, and the subsequent rate of evaporation, when a mercury pool is exposed to an opposing liquid air cooled condensing target.

Regression surfaces for estimated reflection coefficients

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
The distributions of the estimates of reflection coefficients depart considerably from normality, even using moderately long data records. As a result of this, the interdependencies among those estimates are nonlinear. The authors examine the nature of those nonlinear relationships by studying the regression surfaces of the estimated reflection ...

Reflection and Transmission Coefficients for a Diffused Interface

Applied Optics, 1968
The reflection and transmission coefficients for an inhomogeneous layer separating two semiinfinite homogeneous media are examined. Two different cases are investigated, each with a different permittivity profile for the inhomogeneous layer. Detailed examination of these coefficients reveals the relation of their magnitude and phase to the wavelength ...
