Converting Sabine absorption coefficients to random incidence absorption coefficients
The Journal of the Acoustical Society of America, 2013Absorption coefficients measured by the chamber method are referred to as Sabine absorption coefficients, which sometimes exceed unity due to the finite size of a sample and non-uniform intensity in the reverberation chambers under test. In this study, conversion methods from Sabine absorption coefficients to random incidence absorption coefficients ...

Absorption Coefficients for Exciton Absorption Lines
Physical Review, 1957The absorption coefficient for excitons is calculated in the effective-mass approximation. The coefficient is shown to be decreased over what one would expect for a collection of free atoms by the factor ${\ensuremath{\epsilon}}^{\ensuremath{-}1}{(\frac{{a}_{0}}{{a}_{B}})}^{3}$, where $\ensuremath{\epsilon}$ is the dielectric constant and $\frac{{a}_{0}

The diffusion coefficient depends on absorption
Optics Letters, 1998The diffusion approximation is widely invoked to model the propagation of light in turbid media. When absorption is not weak in comparison with scattering, there is currently a controversy as to if, and how, the diffusion coefficient depends on absorption.

The Filtration-Absorption Equation with a Variable Coefficient
Differential Equations, 2001The author considers the Cauchy problem \[ u_t=\Delta u^m -c(x,t)u^p, \;(x,t)\in S=\mathbb{R}^N\times \mathbb{R}_+,\quad u(x,0)=u_0(x) \] where \(m>1\), \(p>m\), \(N\geq 1\) and \(c(x,t)\in C^\alpha_{\text{loc}}(S)\) is a nonnegative function positive outside some cylinder ...

Measurement of Low Absorption Coefficients in Crystals
Applied Optics, 1973The measurement of the absorption coefficient of highly transparent materials using Pinnow and Rich's calorimetric technique requires that the material be fabricated into the shape of a cylindrical rod. Since crystalline materials are more readily fabricated into rods with a square cross section, Pinnow and Rich's calorimetric technique is extended to ...
