High‐Density Spectral Analysis for Bi‐Atrial Arrhythmogenic Substrate During Non‐Paroxysmal Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
Analyzing 48 153 CARTOFINDER mapping points revealed that both FoA and RoA sites demonstrated elevated DF deviation (DFD) and RI compared to non‐sites. While both metrics increased progressively with FoA repetitions, high‐repetition RoA sites paradoxically displayed lower values.

Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Analytically Co‐Designed Absorption‐Diffusion Coding Metasurface for RCS Reduction

Microwave and Optical Technology Letters, Volume 68, Issue 10, October 2026.
ABSTRACT This work proposes a novel and simple design method for an absorption‐diffusion metasurface, combining a coding diffusion‐type metasurface with an absorbing layer. The diffusion and absorption properties are obtained through an analytical co‐design methodology derived from a straightforward Smith chart‐based construction.

Understanding higher‐order aberrations in keratoconus

Optometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...
