Graphene aerogels (GAs) are prevailing to solve electromagnetic interference (EMI) issues in next-generation electronic devices. However, the practical EMI shielding application of lightweight GAs is still a great challenge because their structural instability when confronted with complex conditions. Here, we report class ultra-stable excellent and reliable performances. The GA (ρ = 3.7 mg cm−3...

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...

Observation of parity non-conservation in deep-inelastic scattering of polarized electrons from deuterium was reported in an experiment at SLAC in 1978. The events at SLAC and elsewhere leading to the successful search for parity non-conservation in the electromagnetic processes are described.

Although pacemakers and implantable cardioverter-defibrillators (ICDs) are subject to electromagnetic interference (EMI) from many sources, relatively few are capable of causing clinically significant interference. However, in the rapidly evolving technology -driven environment in which we live, new devices that could theoretically cause interference with implanted devices constantly appear bot...

This thesis examines the effects of electromagnetic interference (EMI) and coupling in circuits and systems. The coupling phenomenon is investigated in nonuniform transmission lines and adjacent via structures in microelectronic circuits. Radiation from metallic enclosures with apertures and lined with resistive materials is analyzed. Electromagnetic interference on a larger scale is studied in...

This paper demonstrates that the addition of chemical agents and carbon fibers to cement can greatly enhance the shielding effectiveness of the concrete. In addition to improving the shielding effectiveness, carbon fibers and chemical agents enhance the tensile and flexural strengths significant ly. As both carbon fibers and steel fibers are electrically conductive, both can be added to cement ...

This work analyzes the advantages of broad-band time-domain the electrical measurement applied to electromagnetic interference (EMI) problems. The digital signal processing of EMI measurements allows to emulate in real-time the various modes of conventional analogous equipment. Since time-domain techniques allow processing the amplitude and phasing information of the whole signal spectrum in pa...

Although current lead design and filtering capabilities have greatly improved, Electromagnetic Interference (EMI) from environmental sources has been increasingly reported in patients with Cardiac Implantable Electronic Device (CIED) [1]. Few cases of inappropriate intracardiac Cardioverter Defibrillator (ICD) associated with swimming pool has been described [2]. Here we present a case of 64 ye...

A road map for the long term development of the partial element equivalent circuit (PEEC) method is presented. Emerging areas are pointed out together with a solution strategy. Special attention is given to speed up approaches, mesh generation, and time domain stability. The purpose with the road map is to facilitate a unified development of the method into an electromagnetic modeling method su...
