MODELLING AND ANALYSIS OF PERMANENT MAGNET ELECTRODYNAMIC SUSPENSION SYSTEMS [PDF]

Progress In Electromagnetics Research M, 2014
In this paper, an analytical model of permanent magnet electrodynamic suspension systems (PEDSs) is proposed. Horizontal and vertical magnetic flelds of a permanent magnet (PM) are efiectively approximated by sinusoidal functions. By this means, closed form solutions are obtained for lift and drag forces of PEDSs for the flrst time.

Reducing the Power Consumption of the Electrodynamic Suspension Levitation System by Changing the Span of the Horizontal Magnet in the Halbach Array

Energies, 2021
In high-speed magnetic railways, it is necessary to create the forces that lift the train. This effect is achieved by using active (EMS) or passive (EDS) magnetic systems.

Large, Long‐Lasting Mid‐Latitude Geomagnetically Induced Currents During a Moderate Geomagnetic Storm

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetically Induced Currents (GICs) are a key space weather hazard to ground‐based infrastructure, and can cause mis‐operation or even equipment failure. The solar wind interacts with the Earth's geomagnetic field, causing the magnetic field at ground level to vary with time.

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 204-223, June 2026.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Active Particles in Tunable Compressible Environments

Small Science, Volume 6, Issue 5, May 2026.
Gold‐capped active microparticles powered by electric fields plough their way through a matrix of repulsive spheres, shoveling them aside. At high densities and field strengths, an initial strong direction fluctuation may compress the matrix asymmetrically and lead to an asymmetric reaction favoring sustained turns to the same side (spontaneous ...

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly
