Topological Parametric Amplification of Structured Interface States

open access: yesNanophotonics, Volume 15, Issue 21, 12 November 2026.
Topological interface states in a trimer waveguide lattice support parametric amplification while light continuously exchanges energy between two interface waveguides. Despite the reduced spatial overlap of the interacting fields, an ultra‐silicon‐rich nitride (USRN) platform yields a signal gain of 3.5 dB.

Multiscale PA6 Composites Reinforced With Recycled Carbon Fibers and Graphene: Synergistic Effects on Mechanical and Electromagnetic Behavior

open access: yesPolymer Composites, Volume 47, Issue 21, Page 19700-19717, 10 November 2026.
Synergistic effects of recycled carbon fibers and GNP on the mechanical and electromagnetic performance of multiscale PA6 composites. ABSTRACT The mechanical recycling of carbon fiber‐reinforced thermoplastics (CFRTs) generally degrades the mechanical properties of the resulting composites, primarily due to fiber length reduction. To partially overcome

Femtosecond‐Laser‐Induced Selective Etching in a Mid‐Infrared Glass

open access: yesAdvanced Photonics Research, Volume 7, Issue 11, November 2026.
Using femtosecond‐laser‐assisted chemical etching in 1 mol L−1 HCl, selective etching is demonstrated for the first time in a MIR‐transmitting gallate glass, yielding etching rates exceeding 4000 µm h−1 and aspect ratios up to ~15. Thermal modeling and annealing experiments suggest the involvement of oxygen‐related defects in the etching mechanism ...

Simulating Flow Rate Effects on Fields in Microwave Fixed‐Bed Reactors

open access: yesChemical Engineering &Technology, Volume 49, Issue 11, November 2026.
A 3D multiphysics model couples microwave heating with transient heat and fluid transport in a fixed‐bed reactor. Increasing gas flow lowers peak temperature and shifts the heated region downstream, whereas microwave heating also induces buoyancy‐driven natural convection in the cavity.

Dual-Band Notch Filter Based on Twist Split Ring Resonators

open access: yesInternational Journal of Antennas and Propagation, 2014
A novel dual-band rectangular waveguide notch filter is experimentally investigated in this paper. Such filter is realized by integrating two pairs of split ring resonators (SRRs) printed on the two sides of a dielectric slab with twist angles and ...
