Towards Electrothermal Optimization of a HVDC Cable Joint Based on Field Simulation

open access: yesEnergies, 2021
Extruded high-voltage direct current cable systems transmit electric power over long distances. Numerical field simulation can provide access to the internal electrothermal behavior of cable joints, which interconnect cable sections.

Modeling and Analytical Description of Parasitic Probe Effects in Measurements of Conductor-Backed Coplanar Waveguides [PDF]

open access: yesAdvances in Radio Science, 2023
On-wafer measurements are of fundamental importance to the characterization of active and passive devices at millimetre-wave frequencies. They have been commonly known to be ambitious and challenging due to the occurrence of parasitic effects originating

Invariants of the electromagnetic field [PDF]

open access: yesJournal of Mathematical Physics, 2014
We present a constructive proof that, in electrodynamics, all of the gauge-invariant Lorentz scalars and pseudoscalars can be expressed as functions of the quadratic ones.

Generation of Electromagnetic Field by Microtubules [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
The general mechanism of controlling, information and organization in biological systems is based on the internal coherent electromagnetic field. The electromagnetic field is supposed to be generated by microtubules composed of identical tubulin heterodimers with periodic organization and containing electric dipoles.

"Good-but-Imperfect" electromagnetic reverberation in a VIRC [PDF]

open access: yes, 2011
Novel theoretical probability density functions (PDF) of electromagnetic fields inside reverberation chambers operating in a “good-but-imperfect‿ regime have been recently reported. The present work reports on the application and assessment of these PDFs

Quasi‐3D magnetic field simulation of superconducting devices with translational symmetry

open access: yesIET Science, Measurement & Technology, 2021
This work presents a quasi‐three‐dimensional (Q3D) approach for the magnetic field simulation in superconducting devices. First‐order two‐dimensional finite‐element edge functions in the model's cross‐section are combined with one‐dimensional orthogonal ...

A System for Monitoring of Broadband FMR Phenomenon in Low-Carbon Steel Films Subjected to Deformations

open access: yesSensors, 2021
Stresses and deformations are some of the main factors influencing the mechanical and magnetic properties of steels. Resonance methods, based on the utilization of high-frequency electromagnetic fields, are the ones that can provide information about the

Advanced Modelling Techniques for Resonator Based Dielectric and Semiconductor Materials Characterization

open access: yesApplied Sciences, 2020
This article reports recent developments in modelling based on Finite Difference Time Domain (FDTD) and Finite Element Method (FEM) for dielectric resonator material measurement setups. In contrast to the methods of the dielectric resonator design, where
