Electromagnetic Design and Analysis of Permanent Magnet Linear Synchronous Motor

open access: yesEnergies, 2022
Since permanent magnet linear synchronous motors are widely used in fatigue testing, in this paper, the thrust of a permanent magnet linear synchronous motor (PMLSM) is amplified more than 10 times by the method of resonance.

Feedback controller designs for an electromagnetic micromanipulator

open access: yesProceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2019
Magnetic micromanipulators are capable of generating wide range of magnetic forces to manipulate magnetic microparticles for biomedical applications. In this study, a multipole magnetic micromanipulator system including electromagnets, driver circuitry and control unit is designed, modeled and implemented. The micromanipulator can produce a broad range

ELECTROMAGNETIC COMPATIBILITY DESIGN FOR KOMPSAT-2 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2003
It is quite essential that requirements allocation and analysis would be done for the electromagnetic compatibility (EMC) of all units when designing a satellite. Although KOMPSAT-2 inherits relatively large portions of the electrical designs from KOMPSAT-1, it has a new instrument and different combinations of sensors and actuators as well as their ...

Design, concepts, and applications of electromagnetic metasurfaces [PDF]

open access: yesNanophotonics, 2018
Abstract The paper overviews our recent work on the synthesis of metasurfaces and related concepts and applications. The synthesis is based on generalized sheet transition conditions (GSTCs) with a bianisotropic surface susceptibility tensor model of the metasurface structure. We first place metasurfaces in a proper historical context
