electromagnetic forming is a high energy rate forming process. in this process, an electromagnetic lorentz body force is used for deformation of products. in this article, electromagnetic forming process was simulated for assembly of parts as an innovative method. in this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...

This paper presents the electromagnetic interference and electromagnetic susceptibility characteristics of the railway telecommunication intra-subsystem. These are for assessing the electromagnetic compatibility inside the railway telecommunication subsystem and providing input data for electromagnetic compatibility analysis of other subsystems (intra-system analysis). This paper shows the opti...

Human body communication (HBC) is a promising wireless technology that uses the human body as part of the communication channel. HBC operates in the near-field of the high frequency (HF) band and in the lower frequencies of the very high frequency (VHF) band, where the electromagnetic field has the tendency to be confined inside the human body. Electromagnetic interference poses a serious relia...

General expressions to obtain the electromagnetic energy flow lines behind interference gratings are derived in the case where the incident light consists of a polarized monochromatic plane wave. These flow lines show how the electromagnetic energy redistributes in space (behind the grating) until the Fraunhofer regime is reached, thus providing an interpretation based on photon paths for the p...

This paper put forward a finite element method to study the radio transmission in tunnel electromagnetic environment. The author makes use of software simulation to study the rectangular tunnel model. When varying the electric parameters of tunnel wall, ceiling and floor, this may somewhat influence the propagation characteristics of electromagnetic wave.In order to study the interference prope...

A fiber access communication system is developed to cater for the need of network communications industry. In this paper, the basic framework of the system is described; with regards to the characteristics of the system, firstly the electromagnetic interference approaches of the whole system are discussed. Emphasis is laid on the engineering analysis and discussion of the interference sources o...

This work addresses the assessment of the electromagnetic disturbance induced by a composite barrier—fencing airport structures—to radio-communication electromagnetic waves. The barrier is composed of glass fiber reinforced polymer GFRP tubular elements installed into a concrete base. Based on the electromagnetic properties of constituent materials, numerical analyses describing the electromagn...

There are worries about suspected electromagnetic interference with aircraft systems from electronic devices used by passengers. Some first-hand incident reports from colleagues are included. The phenomenon seems to be hard to pin down -colleagues explain why. It may be that the current regulatory situation affects reporting and investigation of suspected incidents. Finally, I suggest some ways...

This is a short comment on the editorial on Electromagnetic Interference in Implantable Rhythm Devices The Indian Scenario in the July-September issue of the journal.1 Regarding the statement: "Systems working at 0.5 Tesla are available in the country so that it may be considered in such situations..." , though the author conveys his point, it gives reader a feeling that 0.5 Tesla magnetic reso...

BACKGROUND Over 140 million iPads(®) have been sold worldwide. The iPad2(®), with magnets embedded in its frame and Smart Cover and 3G cellular data capability, can potentially cause electromagnetic interference in implantable cardioverter defibrillators. This can lead to potentially life-threatening situations in patients. The goal of this study was to determine whether the iPad2(®) can cause ...
