Electromagnetic interference risk analysis
IEEE Engineering in Medicine and Biology Magazine, 2008Daily mitigation of and planning for intentional or unintentional EMI should be a part of a medical facilities ongoing spectrum management just as annual condition and risk assessments are performed at other facilities. A reasonable supply of spare electronic components should be stored safely on site and readily available (network switches, wireless ...

Isogeometric Analysis for Electromagnetic Problems
IEEE Transactions on Magnetics, 2010Isogeometric analysis (IGA) is a novel discretization method, introduced by Hughes, which is based on nonuniform rational B-splines (NURBS). Among other features, IGA uses directly the geometry description coming from computer-aided design software without approximation, and the analysis is performed using shape functions of variable (possibly high ...

Design and Electromagnetic Analysis of SFPM
2016 International Conference on Cybernetics, Robotics and Control (CRC), 2016Topology and operation principle of a novel doublysalient permanent magnet motor (DSPM) named switchfluxing permanent magnet motor (SFPM) are analyzed. Atfirst, based on the design principle of DSPM, originaldimensions are determined. Secondly, after the physical modelof motor is built, based on finite element analysis, the magneticfield distributions,

Evaluation of countermeasures against electromagnetic analysis
2009 International Symposium on Electromagnetic Compatibility - EMC Europe, 2009The scope of this paper is twofold. (1) It aims at introducing a low cost near-field mapping system. This system scans automatically and dynamically, in both time and frequency domains, the magnetic field emitted by integrated circuits during the execution of any repetitive sequence of instructions.

Sensitivity analysis of crosswell electromagnetics
Geophysics, 1992Abstract Sensitivity studies for low-frequency crosswell electromagnetics (EM) show that the region contributing to the response is quasi-ellipsoidal in shape and encompasses both source and receiver. The strongest response originates from the immediate vicinity of the source and receiver, but measurable contributions are also ...

Electromagnetic analysis of RFEC differential probes
IEEE Transactions on Magnetics, 1993A differential probe (DP) for defect detection in the remote field eddy current (RFEC) technique is proposed. The analysis of the DP response to a sinusoidal steady-state excitation and a sinusoidal pulse excitation has been carried out by an equivalent network model, which allows easy modeling of axisymmetric defects.

Methods of Electromagnetic Field Analysis*
Bell System Technical Journal, 1948This paper presents a discussion of ideas involved in various mathematical methods of electromagnetic field analysis and of the inter-relations between these ideas. It stresses the points of contact between circuit and field theories and their mutually complementary character. While the field theory focuses our attention on the electromagnetic state as
