Histories Electromagnetism [PDF]
Journal of Mathematical Physics, 2003 Working within the HPO (History Projection Operator) Consistent Histories formalism, we follow the work of Savvidou on (scalar) field theory and that of Savvidou and Anastopolous on (first-class) constrained systems to write a histories theory (both ...

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

Minkowski's lost legacy and hadron electromagnetism
Physics 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.

A Wideband Feed Network for Vivaldi Antenna Arrays
International 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.

A Subcell Finite-Difference Time-Domain Implementation for Narrow Slots on Conductive Panels
Applied 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]
EPJ 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 ...
