Modelling of electromagnetic interferences produced by a railgun

IEEE Transactions on Magnetics, 1993
The electromagnetic fields radiated by a railgun during its operation are evaluated at different points around the launcher. The radiation is determined, assuming a temporal and spatial form of the current in the plasma arc, and integrating the Maxwell equations directly in the time domain.

Materials for Electromagnetic Interference Shielding

Journal of Materials Engineering and Performance, 2000
Materials for the electromagnetic interference (EMI) shielding of electronics and radiation sources are reviewed, with emphasis on composite materials and resilient EMI gasket materials, which shield mainly by reflection of the radiation at a high frequency.

Electromagnetic interference: A radiant future!

2015 IEEE 5th International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 2015
Although Electromagnetic Interference and Electromagnetic Compatibility are well established domains, the introduction of new technologies results in new challenges. Changes in both measurement techniques, and technological trends resulting in new types of interference are described.

A technique for electromagnetic interference measurements on instruments

IEEE Transactions on Instrumentation and Measurement, 1998
The aim of this paper is to highlight the problems that arise when the immunity of measurement instruments to power line voltage disturbances has to be evaluated. The lack of an international product standard puts at the user's disposal only some basic standards which, in giving only general criteria for test result classification, make it difficult to

Intentional Electromagnetic Interference

2009
Intentional electromagnetic interference (IEMI) is an extension of the work by the well-known electromagnetic compatibility (EMC) and electromagnetic interference (EMI) communities. Additional threats have recently surfaced that suggest that various individuals and groups can build devices to intentionally cause electronic systems to fail.

Electromagnetic Interference and Compatibility

2014
EMI requires a (1) source of energy, (2) a receptor or victim circuit or system, and (3) some coupling path for the energy to get from one place to the other. If there is no energy source, there is no EMI, and if there is no coupling path, there is no EMI.

Statistics as a toolbox for electromagnetic interferences modeling

2013 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2013
Summary form only given. Safety and security of critical infrastructures rely on the robustness of the involved systems to electromagnetic interferences from the electromagnetic compatibility point of view. In recent years, documented electromagnetic interferences attacks have demonstrated the susceptibility of devices (F.

Electromagnetic Interference (EMI)

2002
Electric and magnetic signals originating outside of a defibrillator may affect its operation, a phenomenon known as electromagnetic interference (EMI). EMI usually refers to interference from environmental electromagnetic instrumentation and should be distinguished from other sources of electromagnetic noise causing ICD malfunction (Table 1).

Electromagnetic Interference and Electromagnetic Compatibility Test Technology

2010 International Conference on Machine Vision and Human-machine Interface, 2010
With the extensive application of electronic equipment, issues from electromagnetic compatibility caused by electromagnetic interference will directly affect the normal operation of the system or equipment. In this paper, the electromagnetic interference on the basis of research and analysis the two typical interference source-- the inverter and ...
