Polarization converters in highly birefringent microfibers

open access: yesOptics Express, 2014
A novel type of polarization converters (PCs) based on highly birefringent (Hi-Bi) microfibers is presented. Analytical formulation based on the Jones Matrix method and a numerical code based on the Full Vectorial Finite Difference Beam Propagation Method are developed to analyze the polarization evolutions in such PCs.

Foundational Machine‐Learning Interatomic Potential for Simulating Chemically Complex Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
We apply a foundational machine‐learning interatomic potential based on the graph atomic cluster expansion (GRACE) to simulate the commercial Ni‐based single‐crystal superalloy CMSX‐4. Hybrid Monte‐Carlo/molecular dynamics sampling resolves short‐range order in the γ phase and L12 sublattice occupancies in the γ’ phase and connects them to stacking ...

Design of WideBand Transmission Polarization Converters

open access: yes2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials), 2019
A designing tool for wideband transmission polarization converting surfaces is presented. The optimized wideband polarizer comprises several metasurface layers whose unit cell is gradually rotated. The analysis is based on an analytical transmission line model of the multilayer structure with anisotropic elements.
