Disentangling Optical Transport Regimes in Hyperuniform Photonic Materials Via Transverse Beam Spreading

Advanced Optical Materials, EarlyView.
Light in a disordered dielectric slab spreads, confines, or is blocked depending on the transport regime. Studying the transverse spreading of a focused beam at the output face identifies diffusion, Anderson localization, and photonic bandgaps, and yields the localization length from a single slab thickness.

Axial asynchrony between radial mass redistribution and hottest-rod transition in supercritical CO2 flow through a tightly packed 19-rod bundle

In compact reactors cooled by supercritical carbon dioxide (sCO2), bundle-averaged flow and thermal quantities cannot identify the hottest rod when the coolant crosses the pseudocritical region.
