Multiplexed supercell metasurface design and optimization with tandem residual networks

open access: yesNanophotonics, 2021
Complex nanophotonic structures hold the potential to deliver exquisitely tailored optical responses for a range of applications. Metal–insulator–metal (MIM) metasurfaces arranged in supercells, for instance, can be tailored by geometry and material ...

Supercell refinement: a cautionary tale [PDF]

open access: yesActa Crystallographica Section D Structural Biology, 2019
Theoretically, crystals with supercells exist at a unique crossroads where they can be considered as either a large unit cell with closely spaced reflections in reciprocal space or a higher dimensional superspace with a modulation that is commensurate with the supercell.

Observation of stacking engineered magnetic phase transitions within moiré supercells of twisted van der Waals magnets [PDF]

open access: yesNature Communications
Recent demonstrations of moiré magnetism, featuring exotic phases with noncollinear spin order in the twisted van der Waals (vdW) magnet chromium triiodide CrI3, have highlighted the potential of twist engineering of magnetic (vdW) materials.

Polychromatic metasurfaces for complete control of phase and polarization in the mid-infrared

open access: yesLight: Science & Applications, 2023
Multifunctional metasurfaces based on wavelength-decoupled supercells are experimentally demonstrated, enabling new regimes of optical control for arbitrary orthogonal polarizations at different wavelengths.

Strange Storms: Rainfall Extremes From the Remnants of Hurricane Ida (2021) in the Northeastern US

open access: yesWater Resources Research, 2023
On 1 September 2021, the remnants of Hurricane Ida transformed into a lethal variant of tropical cyclone in which unprecedented short‐duration rainfall from clusters of supercells produced catastrophic flooding in watersheds of the Northeastern US. Short‐

Trapping Capability of Small Vacancy Clusters in the α-Zr Doped with Alloying Elements: A First-Principles Study

open access: yesCrystals, 2022
Zirconium alloys are subjected to a fast neutron flux in nuclear reactors, inducing the creation of a large number of point defects, both vacancy and self-interstitial.

Radar Signatures in Tropical Cyclone Tornadic and Nontornadic Supercells [PDF]

open access: yes, 2023
Tropical cyclones (TCs) contain highly-sheared environments that are conducive for supercell thunderstorms. These TC supercells sometimes produce tornadoes, often with little warning.

Analysis of a Case of Supercellular Convection over Bulgaria: Observations and Numerical Simulations

open access: yesAtmosphere, 2019
A long-lived supercell developed in Northwest Bulgaria on 15 May 2018 and inflicted widespread damage along its track. The first part of this article presents a detailed overview of the observed storm evolution. Doppler radar observations reveal that the
