Active Shielding System for ELF Magnetic Fields
IEEE Transactions on Magnetics, 2015This paper focuses on the development of a low-cost system, based on Arduino, for the active shielding of magnetic fields generated by power systems at industrial frequency. The modeling of the source, the design and the optimization of the shielding loop, and, finally, the hardware (microcontroller, sensors, driven voltage source, etc.) and the ...

Active Shielding Design for Wireless Power Transfer Systems
IEEE Transactions on Electromagnetic Compatibility, 2019The shielding technique by active coils is proposed to mitigate the magnetic field produced by a wireless power transfer (WPT) system based on near field coupling. General guidelines are provided for the active shielding design to shield the source for emission reduction or to shield the victim for immunity enhancement.

Active magnetic radiation shielding system analysis and key technologies
Life Sciences in Space Research, 2015Many active magnetic shielding designs have been proposed in order to reduce the radiation exposure received by astronauts on long duration, deep space missions. While these designs are promising, they pose significant engineering challenges. This work presents a survey of the major systems required for such unconfined magnetic field design, allowing ...

Layered shielding design for an active neutron interrogation system [PDF]
Radiation Physics and Chemistry, 2016 Abstract The use of source and detector shields in active neutron interrogation can improve detector signal. In simulations, a shielded detector with a source rotated π/3 rad relative to the opening decreased neutron flux roughly three orders of magnitude. Several realistic source and detector shield configurations were simulated.

Actively shielded transportable SMES-systems
IEEE Transactions on Magnetics, 1996Previous investigations on active shielding of SMES systems have proved to be successful in reducing the stray field. It was shown that the stray field of a single solenoidal SMES can be diminished by adding shielding solenoids under the condition that the sum of the magnetic dipole moments of all coils equals zero.

2021 29th Iranian Conference on Electrical Engineering (ICEE), 2021
We proposed a simple method to enhance shielding factor of our previously proposed bi-stage active shield system employed in a SQUID-based magnetocardiography system. The additional proposed design is optimized for canceling the power-line magnetic interference field to provide a calmer magnetic environment for the bi-stage active shield.

Active shielding suitable for electron beam lithography systems
Digest of INTERMAG 2003. International Magnetics Conference (Cat. No.03CH37401), 2003This paper describes suitable active shielding (AS) for electron-beam lithography systems (EBLSs). The optimal position of a reference sensor (RS), of which the signal is used to feed a current into a canceling coil (CC), is discussed. Preliminary experiments using an EBLS verification model and three-dimensional (3-D) magnetic field computations were ...

Active Shielding Applied to an Electrified Road in a Dynamic Wireless Power Transfer (WPT) System [PDF]
Energies, 2020 An active coil system is proposed to shield the magnetic field produced by a dynamic wireless power transfer (WPT) system used to power electric vehicles (EVs) in motion. The considered dynamic WPT is based on an electrified road with many short-track pads.
