Název v původním jazyce

Mesoscale modeling of polycrystalline light transmission

Popis výsledku v původním jazyce

Recent advances in polycrystalline ceramic synthesis have established fabrication routes for producing dense ceramics with grain size on the order of few nanometers. Light transmission properties and, specifically, the high transparency of birefringent nanocrystalline ceramics cannot be captured by classical geometrical optics theory. In this investigation, we combine the Raman-Viswanathan wave-retardation theory with finite element method (FEM) based numerical simulations to develop an approach for predicting the refractive index variation within and real in-line transmission through relevant optical materials. This approach is validated on non-cubic (and, therefore birefringent) Al2O3 and MgF2 polycrystalline ceramics, by comparing the computed light transmission to experimental transmission measurements.
