Hexagonal Hollow‐Core Photonic Crystal Fiber for High‐Sensitivity Terahertz Glucose Detection

Journal of Biophotonics, Volume 19, Issue 8, August 2026.
A novel hexagonal hollow‐core photonic crystal fiber (HPhCF) operating at 2.2 THz is proposed for rapid, non‐invasive detection of urinary glucose. The Zeonex‐based hollow‐core architecture enhances light‐analyte interaction, enabling 96.90% relative sensitivity while maintaining ultra‐low confinement loss and low effective material loss.

Black Phosphorus/Ferroelectric CuInP2S6 Heterostructures Empowering Nonvolatile Photonic Convolutional Computing

Laser &Photonics Reviews, Volume 20, Issue 16, 21 August 2026.
ABSTRACT The growing demands of artificial intelligence require new energy‐efficient and nonvolatile computing paradigms. To meet this challenge, we demonstrate a foundational device platform for optical fiber computing that targets the signal decay and power consumption bottlenecks of conventional systems.

Surface roughness impact of 3D Ti-alloy printed WR-10 waveguide and rectangular horn antenna at W-band (75-110 GHz)

Micro and Nano Systems Letters
To investigate the effect of the surface roughness of 3D-metal-printed sub-THz components, the WR-10 3-inch-long waveguide and 24 dBi rectangular horn antenna were 3D-metal-printed using a titanium alloy powder and a high-resolution 3D metal printer. The

High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

Small, Volume 22, Issue 46, 18 August 2026.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

Analysis of leaky-wave antenna based on partially-filled rectangular waveguide

Известия высших учебных заведений России: Радиоэлектроника, 2015
A leaky-wave antenna based on the partially-filled rectangular waveguide with transverse slots is investigated. Using tensor Green’s functions for antenna radiation analysis is suggested.

Engineering and Tuning of High Quality Hexagonal Boron Nitride Nanophotonic Resonators

Small, Volume 22, Issue 47, 21 August 2026.
The manuscript explores nanofabrication protocols for photonic crystal cavities and microdisk resonators from hexagonal boron nitride. High Q cavities are fabricated and their resonances are controllably tuned. The work is important for future realization of quantum technologies with hexagonal boron nitride.

Numerical Anisotropy and Band‐Gap Formation in Finite Element Wave Propagation: Analysis and Mitigation Using Spline‐Based Elements

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Numerical anisotropy and dispersion are inherent consequences of spatial discretization in finite element modeling of wave propagation. In two‐dimensional problems, these effects manifest not only as direction‐dependent phase and group velocities but also as angularly dependent numerical band gaps that may entirely suppress wave propagation ...
