Refraction and Reflection of Diffusion Fronts [PDF]
Physical Review Letters, 2003 Diffusion waves form the basis of several measurement technologies in materials science as well as in biological systems. They are, however, so heavily damped that their observation is a real challenge to the experimentalist. We show that accurate information about the refraction-like and reflection-like behavior of diffusion waves can be obtained by ...

Morphological and optical properties of porous hydroxyapatite/cornstarch (HAp/Cs) composites
Journal of Materials Research and Technology, 2020 This paper presents the correlation between the morphological characteristics and the diffuse reflectance (optical properties) of the porous hydroxyapatite/cornstarch (HAp/Cs) composites with various starch proportions (30, 40, 50, 60, 70, 80 and 90 wt%).

ReDDLE-Net: Reflectance Decomposition for Directional Light Estimation
Photonics, 2022 The surfaces of real objects can visually appear to be glossy, matte, or anywhere in between, but essentially, they display varying degrees of diffuse and specular reflectance.

Reflectometers for Absolute and Relative Reflectance Measurements in the Mid-IR Region at Vacuum
Sensors, 2021 We demonstrated spectral reflectometers for two types of reflectances, absolute and relative, of diffusely reflecting surfaces in directional-hemispherical geometry.

Influence of refractive index matching on the photon diffuse reflectance [PDF]
, 2002 Photon migration in a randomly inhomogeneous, highly scattering and absorbing semi-infinitemediumwith a plane boundary is considered by aMonte Carlo (MC) technique. The employed MC technique combines the statistical weight scheme and real photon paths

Analysis of petroleum-contaminated soils by diffuse reflectance spectroscopy and sequential ultrasonic solvent extraction-gas chromatography [PDF]
, 2014 In this study, we demonstrate that partial least-squares regression analysis with full cross-validation of spectral reflectance data estimates the amount of polycyclic aromatic hydrocarbons in petroleumcontaminated tropical rainforest soils.

On reflected diffusions in cones and cylinders
Ukrains’kyi Matematychnyi Zhurnal, 2023 UDC 519.21 Let X be a diffusion in a cone with oblique reflection at the boundary. We study the question whether X reaches a vertex of the cone for a finite time with positive probability. We propose new probabilistic method of investigation connected with the long-term behavior of a diffusion reflected in a cylinder.
