Physics-Guided CNN Detection of Crack-Associated Events from Embedded Fiber Bragg Grating Sensors [PDF]

open access: yesSensors
Crack detection in composite structures remains a central challenge in structural health monitoring, particularly when sensing must rely on a small number of embedded multiplexed fiber Bragg gratings (FBGs).

Minkowski's lost legacy and hadron electromagnetism

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2023
We revisit Minkowski's lost legacy on relativistic electromagnetism in order to resolve long-standing puzzles over the charge distribution of relativistic systems like hadrons.

Transverse force sensing with a uniform FBG and unpolarized light via machine learning [PDF]

open access: yesScientific Reports
In this paper, we report that a uniform fiber Bragg grating (FBG), interrogated with broadband light, can be used to reliably measure transverse force through the analysis of its unpolarized reflected amplitude spectrum.

Astrocyte-mediated higher-order control of synaptic plasticity [PDF]

open access: yesCommunications Biology
The dynamics of higher-order topological signals are increasingly recognized as a key aspect of the activity of complex systems. A paradigmatic example are synaptic dynamics: synaptic efficacy changes over time driven by different mechanisms.

Long-term Transmission Characteristics of CYTOP Fiber Exposed to Gamma Radiation [PDF]

open access: yesEPJ Web of Conferences, 2021
We investigated post-irradiation variations of the radiation induced attenuation (RIA) of polymer perfluorinated (CYTOP) optical fiber exposed to gamma radiation.

A Wideband Feed Network for Vivaldi Antenna Arrays

open access: yesInternational Journal of Antennas and Propagation, 2022
A wideband feed network for a Vivaldi antenna array is presented. A limitation of current wideband antenna arrays is the bandwidth of either the feed network or the antenna element.

Compact 0.5–18 GHz double‐ridged guide horn antenna

open access: yesIET Microwaves, Antennas & Propagation, 2021
Broadband double‐ridged guide horn (DRGH) antennas are extensively used in antenna measurement and electromagnetic compatibility and interference testing, especially the 1–18 GHz DRGH antenna which is widely accepted as a standard for this band.

A Subcell Finite-Difference Time-Domain Implementation for Narrow Slots on Conductive Panels

open access: yesApplied Sciences, 2023
Efficiently modeling thin features using the finite-difference time-domain (FDTD) method involves a considerable reduction in the spatial mesh size. However, in real-world scenarios, such reductions can lead to unaffordable memory and CPU requirements ...

Surface Plasmon Resonance sensor based on a D-shaped photonic crystal fiber with a bimetallic layer [PDF]

open access: yesEPJ Web of Conferences, 2020
The investigation of a D-shaped photonic crystal fiber sensor with a bimetallic layer for operation at the visible and infrared spectra is presented. The bimetallic layer is composed by silver and gold slabs deposited adjacently on the flat face of the ...

Dimensional reduction of electromagnetism [PDF]

open access: yes, 2022
We derive one- and two-dimensional models for classical electromagnetism by making use of Hadamard’s method of descent. Low-dimensional electromagnetism is conceived as a specialization of the higher-dimensional one, in which the fields are uniform along
