Triple Space‐Polarization On–Off‐Key Modulation With AlN‐Based Tri‐Focal Metalens
An AlN tri‐focal metalens made of high‐temperature‐annealed AlN by integrating zone‐plate null rings into a polarization‐selective bifocal metalens. The incident light will be focused into two or three foci on the focal plane, each with a distinct polarization state.

Polymer Brushes Govern Defect‐Selective Oxidative Etching of Penta‐Twinned Gold Nanorods
Polymer brushes act as active interfacial regulators of oxidative etching, directing it to crystallographic defects. In penta‐twinned gold nanorods, defect–ligand interplay localizes etching to defect regions and induces surface corrugations on the long nanorod sides. This work establishes a framework for programmable nanoengineering of the surfaces of

Multi‐Objective Inverse Design of a Dual‐Narrowband Thermal Emitter for Optical Gas Sensing
A lithography‐free, wafer‐scale dual‐narrowband thermal emitter is developed using a multi‐objective inverse design framework. It comprises an aperiodic Si/SiO2 dielectric multilayer deposited on a TiN refractory conductive ceramic film. Its dual emission peaks match characteristic absorption bands of CH4 and NO2 and enhance responses to both gases ...

Analysis of electromagnetic wave propogation using 3D finite-difference time-domain methods with parallel processing. [PDF]
The 3D Finite-Difference Time-Domain (FDTD) method simulates structures in the time-domain using a direct form of Maxwell’s curl equations. This method has the advantage over other simulation methods in that it does not use empirical approximations ...

Large Rabi Splitting Driven by Plasmon‐Enhanced Hybrid Anapole States in Si–Au–WSe2 Heterostructures
A silicon hybrid‐anapole microcavity coupled with a plasmonic array enables tripartite strong coupling with WSe2 excitons. Spatially extended field enhancement and coherent cavity–plasmon hybridization strengthen light–matter interactions, producing a giant 330 meV Rabi splitting at room temperature and offering a compact platform for low‐exciton ...

Decoupled Spectral Tuning and Polarization Locking in Twisted α $\alpha $‐MoO3 Polaritonic Crystals
We introduce a deterministic design strategy employing twisted bilayer α $\alpha $‐MoO3 ${\text{MoO}}_{3}$ polaritonic crystals to decouple infrared spectral and polarization degrees of freedom. Although adjusting the interlayer twist angle tunes the absorption spectra, the maximum absorption axis remains robustly locked to the patterned layer's ...
