New elements within finite element modeling of magnetostriction phenomenon in BLDC motor

Open Physics, 2020
Reluctance forces are the main cause of vibration in electrical machines. The influence of magnetostriction is still the matter of controversy. In the article, program Ansys (typical for finite element method) was used to analyze stator deformation due ...

Single‐Pulse Nanomorphology Governs Laser‐Induced Periodic Surface Structure Formation on Metals

Laser &Photonics Reviews, Volume 20, Issue 2, 22 January 2026.
Ultrashort pulse ablation enables generation of self‐organized periodic structures, where evolving nanomorphology controls pulse‐to‐pulse feedback. In noble metals, nanospikes form after the first pulse and localize surface waves, preventing periodic field distributions and thus suppressing their formation.

Optimizing the Electromagnetic Wave Absorption Performance of MXene@Sm(OH)3 Across the Ku Band Based on Asynchronous Permittivity Regulation

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT The central challenge in the development of high‐performance electromagnetic wave‐absorbing materials lies in achieving an optimal balance between impedance matching and attenuation characteristics. This is particularly critical for purely dielectric absorbers, where precise tailoring of the real (ε′) and imaginary (ε″) parts of the complex ...

Hybrid FEA‐ML Optimization of Passive Low‐Frequency Shields With Eccentric Conductors

Electronics Letters, Volume 62, Issue 1, January/December 2026.
Eccentric conductor plates are proposed for electromagnetic shielding, achieving enhanced shielding effectiveness and an expanded range of high‐performance shielding. ABSTRACT This work proposes an eccentric conductor plate design aimed at overcoming the pervasive issue of diminished shielding effectiveness (SE) at the boundaries of traditional plates,

Ferromagnetically Shielded Fault Current Limiter (FS‐FCL) Evaluation in Power Line

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study introduces a new ferromagnetically shielded FS‐FCL design and its control strategy for limiting and interrupting fault currents. The fully shielded core structure enhances inductance and prevents saturation, enabling an immediate fault response without causing voltage drop during normal conditions.

Viscoelastic Behavior of Polyamide 6–COC Blends: Role of Crystallinity and Frequency‐Domain Modeling

Journal of Applied Polymer Science, Volume 142, Issue 47, December 15, 2025.
Schematic overview of the study: Polyamide 6 (PA6) was blended with amorphous cycloolefin copolymer (COC) via melt blending to systematically tailor crystallinity. The resulting blends were characterized using SEM, DSC, and DMA, enabling construction of frequency‐temperature master curves.
