Photochromic Organic–Inorganic Material for Focusable Adaptive Lenses Fabrication

Advanced Photonics Research, EarlyView.
This study investigates a zirconia‐based hybrid organic–inorganic material incorporating dithienylethene molecules for adaptive optics. It offers excellent photochromic properties, thermal stability, and adjustable thickness, enabling effective refractive index modulation.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

On a generalization of close-to-convex functions

, 2014
A motivation comes from {\em M. Ismail and et al.: A generalization of starlike functions, Complex Variables Theory Appl., 14 (1990), 77--84} to study a generalization of close-to-convex functions by means of a $q$-analog of a difference operator acting on analytic functions in the unit disk $\mathbb{D}=\{z\in \mathbb{C}:\,|z|<1\}$.

Tuning Surface Phonon Polaritons in One‐Dimensional Complementary Nanostructures via Curvature and Dielectric

Advanced Photonics Research, EarlyView.
Curvature and dielectric is introduced to tune properties of surface phonon polaritons (SPhPs) in complementary nanostructures: nanowire (NW) and nanohole (NH). It is found that NH complements the frequency band range of SPhP of NW. Frequency‐band subinterval of the SPhP in NHs and NWs can be tuned by dielectric.

Analytical Description of Nanowires: Morphing Wurtzite Structure Cross Sections to Match Arbitrary Convex Shapes

Advanced Theory and Simulations, EarlyView.
Analytic morphing of wurtzite nanowire cross sections to arbitrary shapes yields numbers of nanowire atoms, of bonds between these and of nanowire interface bonds, plus the nanowire cross section area. The ratios of above variables help to interpret any spectroscopic nanowire data which depend on diameter and cross section shape, and can be applied to ...

Properties for Close-to-Convex and Quasi-Convex Functions Using q-Linear Operator

Mathematics
In this work, we describe the q-analogue of a multiplier–Ruscheweyh operator of a specific family of linear operators Iq,ρs(ν,τ), and we obtain findings related to geometric function theory (GFT) by utilizing approaches established through subordination ...

A Meta‐Model for The Design of Soft Pneumatic Actuators Using Neural Networks and Finite Element Analysis

Advanced Theory and Simulations, EarlyView.
Data is generated from finite element simulations and an encoding using a Moore domain. The data is then used to train a meta‐model to predict the soft unit's deformation state depending on its chamber shape and properties as well as the surrounding environment.
