Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2

open access: yesLaser &Photonics Reviews, EarlyView.
A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Ellipsoid‐Based Interval‐Type Uncertainty Model Updating Based on Riemannian Manifold and Gaussian Process Model

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern engineering systems require advanced uncertainty‐aware model updating methods that address parameter correlations beyond conventional interval analysis. This paper proposes a novel framework integrating Riemannian manifold theory with Gaussian Process Regression (GPR) for systems governed by Symmetric Positive‐Definite (SPD) matrix ...

PTQ10‐based organic photodetectors for visible light detection and their tolerance to impurities

open access: yesPolymer International, EarlyView.
PTQ10‐based organic photodetectors were found to be very sensitive to the presence of Pd(PPh3)4 catalyst traces, impacting the transport properties and light detection capacities. Abstract PTQ10 donor polymer has attracted a lot of interest in organic optoelectronics, particularly in the field of organic photovoltaics, owing to its ease of synthesis ...
