Direct measurement of the scattering coefficient. [PDF]
Biomed Opt Express, 2021 In general, the measurement of the main three optical properties (µ a , µ s and g) in turbid media requires a very precise measurement of the total transmission (TT), the total reflection (TR) and the collimated transmission (CT). Furthermore, an inverse algorithm such as inverse adding doubling or inverse Monte-Carlo-simulations ...

Reflection coefficient for superresonant scattering [PDF]
Classical and Quantum Gravity, 2003 We investigate superresonant scattering of acoustic disturbances from a rotating acoustic black hole in the low frequency range. We derive an expression for the reflection coefficient, exhibiting its frequency dependence in this regime.Comment: 7 ...

Universal Statistics of the Scattering Coefficient of Chaotic Microwave Cavities [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2005 We consider the statistics of the scattering coefficient S of a chaotic microwave cavity coupled to a single port. We remove the non-universal effects of the coupling from the experimental S data using the radiation impedance obtained directly from the ...

Bidirectional surface scattering coefficients
Acta AcusticaThe prediction and modeling of sound propagation rely heavily on accurate representations of surface scattering. Traditional scattering coefficients, often based on random-incidence assumptions, fail to capture the directional dependence of sound reflections from rough surfaces.

Multiparametric Quantitative Analysis of Photodamage to Skin Using Optical Coherence Tomography
Sensors, 2023 Ultraviolet (UV) irradiation causes 90% of photodamage to skin and long-term exposure to UV irradiation is the largest threat to skin health. To study the mechanism of UV-induced photodamage and the repair of sunburnt skin, the key problem to solve is ...
