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 ...

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

open access: yesMetalMat, EarlyView.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

Experimental Modal Analysis‐Driven Gaussian Process Regression Modeling of Rectangular Steel Beams With Various Hole Geometries

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

On Order Restricted Inference in Multi‐Step Stage Life Testing for a General Family of Distributions

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Recently, k$$ k $$‐step stage life testing (SLT) has been proposed by Laumen and Cramer (2021) as a natural extension of progressive censoring with fixed censoring times (PC‐FCT) as well as of simple step‐stress accelerated life testing (SSALT).

Mesoscopic light transport in nonlinear disordered media

open access: yesPhysical Review Research
Nonlinear disordered media uniquely combine multiple scattering and second-harmonic generation. Here, we investigate the statistical properties of the nonlinear light generated within such media. We report super-Rayleigh statistics of the second-harmonic

High-speed laser anemometry based on spectrally resolved Rayleigh scattering [PDF]

open access: yes
Laser anemometry in unseeded flows based on the measurement of the spectrum of Rayleigh scattered laser light is reviewed. The use of molecular scattering avoids the well known problems (particle lag, biasing effects, seed generation, seed injection) of ...

Strain Development During Cure of Partially Pre‐Cured Thermosetting Composites Measured With Distributed Fiber Optic Sensors

open access: yesPolymer Composites, EarlyView.
Schematic representation of the beneficial effect of ply pre‐curing on temperature overshoot, internal strain and warpage during cure of thin and thick thermosetting composites. ABSTRACT Detection of manufacturing‐induced defects in thermosetting composites is crucial to guarantee part quality, safety, and improve manufacturing efficiency.
