In a dual-plane compact electromagnetic band-gap (CEBG) microstrip structure, patches are etched periodically in the ground plane to prohibit the propagation of electromagnetic waves in certain frequency bands so as to provide filtering functionality. However, the existence of the etched patches in the ground plane becomes a natural concern for the reason that these structures might be more pro...

Recently, the development of electronic and electric devices has caused an increase in the level of electromagnetic radiation; therefore, the demand for protection against this danger has increased. There are many ways how to ensure the protection of device against electromagnetic interference; however, this paper is devoted just one of the ways, the shielding. The paper is focused on calculati...

We study the pion electromagnetic and γ + π0 → γ transition form factors at intermediate momentum transfer. We calculate soft, nonperturbative corrections to the leading perturbative amplitudes which arise from the qq̄component of the pion wave function. We work in Minkowski space and use a Lorentz covariant, gauge-invariant generalized perturbative integral representation for the qq̄ amplitudes....

Graphene nanostructures were synthesized by Hummer method. 1, 3, 5 and 7 wt% of graphene nanostructures were suspended in certain amount of acetone on a mechanical stirrer and stirred then added to epoxy resin. After 4 hours, solution and Graphene platelets (GPs) were prepared. Nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM ), Fourier transform i...

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...

It is accepted that the electromagnetic interference should be addressed with statistical analysis. Usually the impact of electromagnetic interference on different electronic samples is evaluated and the average immunity level is used as a reference. However, this method does not provide enough information to know the probability of failure to the electromagnetic interferences of an electronic ...

a large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (rf-emfs) such as common mobile phones and magnetic resonance imaging (mri). studies performed on the increased microleakage of dental amalgam restorations after exposure to rf-emfs have further supported th...
