Investigating the Thickness-Dependent Scintillator-PMT Interface Reflection Coefficients with GAGG:Ce3+ Crystals Using the Dual-PMT Setup [PDF]

open access: yesEPJ Web of Conferences, 2023
Recently, it has been shown through both Monte Carlo simulations and experiments that scintillator-PMT interface reflection coefficients could depend on crystal thickness.

A VTI anisotropic media inversion method based on the exact reflection coefficient equation

open access: yesFrontiers in Physics, 2022
Anisotropy is widespread in the Earth’s crust, and VTI (vertical axis symmetry transverse isotropy) anisotropy is common due to stratigraphic pressure. Disregarding anisotropy leads to inaccurate inversion results in VTI media.

Textures Induced by the Coesite‐Stishovite Transition and Implications for the Visibility of the X‐Discontinuity

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The coesite‐stishovite phase transition is considered the most plausible candidate to explain the X‐discontinuity observed at around 300 km depth in a variety of tectonic settings.

Reflection at non-free boundary of a micropolar piezoelectric half-space

open access: yesForces in Mechanics, 2021
This paper presents a study on plane waves propagating in a micropolar piezoelectric material with transverse isotropy. The plane wave solutions of the governing field equations suggest that there exists three coupled plane waves propagating in a ...
