Applications of QSPR and Machine Learning in Molecular Photonics

open access: yesAdvanced Optical Materials, EarlyView.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides

Spatiotemporally Resolved Light Propagation in Transparent Wood

open access: yesAdvanced Optical Materials, EarlyView.
Light propagation mechanism changes from diffusive regime in native, white and delignified wood to near ballistic in transparent wood. Abstract Transparent wood biocomposite (TW) is a sustainable optical material that combines high transmittance with mechanical strength but also exhibits pronounced haze. This haze limits applications where high optical

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems

open access: yesAdvanced Optical Materials, EarlyView.
The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...

A modified reproducing kernel method for a time-fractional telegraph equation

open access: yes, 2017
The aim of this work is to obtain a numerical solution of a time-fractional telegraph equation by a modified reproducing kernel method. Two numerical examples are given to show that the present method overcomes the drawback of the traditional reproducing

Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides

open access: yesAdvanced Optical Materials, EarlyView.
Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.

Numerical Solutions for the Three-Point Boundary Value Problem of Nonlinear Fractional Differential Equations

open access: yesAbstract and Applied Analysis, 2012
We present an efficient numerical scheme for solving three-point boundary value problems of nonlinear fractional differential equation. The main idea of this method is to establish a favorable reproducing kernel space that satisfies the complex boundary ...

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

open access: yesAdvanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...
