A Large-Range and High-Sensitivity Fiber-Optic Fabry–Perot Pressure Sensor Based on a Membrane-Hole-Base Structure

Micromachines
In the field of in situ measurement of high-temperature pressure, fiber-optic Fabry–Perot pressure sensors have been extensively studied and applied in recent years thanks to their compact size and excellent anti-interference and anti-shock capabilities.

Adaptive Metafilm With Scalable Phase‐Tunable Emissivity for Energy‐Efficient Thermal Management

Small, EarlyView.
ABSTRACT Efficient thermal management of enclosed systems through controlled manipulation of radiative cooling power represents a key functionality of adaptive composite metamaterials. Such materials enable precise regulation of heat emission under varying environmental conditions while maintaining scalability and durability.

Metal/Si Nanowire Arrays for Hot Electron Catalysis

Small, EarlyView.
Silicon nanowire arrays enhance plasmon‐driven catalysis by strengthening light–matter interactions on Au and Ag nanostructured coatings. Hotspot accessibility, rather than near‐field intensity alone, governs photocatalytic performance, while Ag nanoshells exhibit superior activity. The work establishes high‐surface‐area Si nanowire arrays as versatile

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Relative Effects of Fabry‐Perot, Mie, and Guided‐Mode Resonance in Periodic Photonic Lattice Physics

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
The physical origins of resonance effects in one‐dimensional periodic photonic lattices are studied to assess the relative roles of Fabry–Perot, Mie, and guided‐mode resonance mechanisms. It is shown that lattice resonance is fundamentally governed by lateral leaky Bloch modes and their coupling to external radiation via guided‐mode resonance.

Band‐Selective, Low‐Dispersion Terahertz Attenuators Based on 3D Bulk Metamaterials Leveraging De‐latticed Cross‐Bar Resonator Ensembles

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
This paper presents 3D bulk metamaterials in which diced cross‐bar meta‐grains are randomly dispersed in a polymer matrix by molding. The de‐latticed composite provides isotropic and band‐selective THz attenuation with over tenfold dispersion suppression compared to the periodic metasurface.

Optical Responses From Zero Optical‐Path‐Length Object

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Velocity‐Tunable Exciton‐Photon Hybridization in Cathodoluminescence

Advanced Functional Materials, Volume 36, Issue 62, 3 August 2026.
Transition‐radiation resonances in suspended thin crystals hybridise with excitonic transitions under free‐electron excitation. By tuning the electron energy, the photonic resonances are continuously detuned across the exciton states, enabling controllable exciton–photon hybridisation below the diffraction limit without altering the system geometry ...

High Performance Durable Vanadium Dioxide Spectral Selective Modulation Smart Windows

Advanced Functional Materials, Volume 36, Issue 63, 6 August 2026.
Crystallinity‐enhanced VO2 nanoparticles with a self‐limited amorphous oxidation shell achieve an order of magnitude durability improvement and high spectral selective modulation performance (luminous transmittance of 28.5%, solar modulation of 10.5%, and mid‐infrared emissivity modulation of 0.5) for smart windows.
