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...

Increasing power density, faster switching and higher currents forces designers to spend more time both considering the effects of electromagnetic interference (EMI) and debugging a design that has EMI problems but is otherwise complete. This paper explains the different types of EMI and their coupling mechanisms and the existing EMI regulations. The most frequent noise sources, transmission pa...

This paper presents a feature analysis of two electromagnetic interference test facilities. The one is an anechoic chamber and the other is a reverberation chamber. And then, this paper reviews problems of the current reverberation chamber, the stirrer. In general, a reverberation chamber uses a stirrer to generate a uniform electric field inside it. However, the stirrer is a big sized unit and...

A simulation technique based on electromagnetic topology EMT theory is proposed for analyzing electromagnetic interference EMI coupling through apertures onto the two-transmission line enclosed within metallic structures. The electromagnetic interactions between apertures and the external-internal interactions were treated through the topological decomposition and the multistep iterative method...

The effect of time-varying electromagnetic fields on electron coherence is investigated. A sinusoidal electromagnetic field produces a time varying Aharonov-Bohm phase. In a measurement of the interference pattern which averages over this phase, the effect is a loss of contrast. This is effectively a form of decoherence. We calculate the magnitude of this effect for various electromagnetic fiel...

In this paper, the frequency responses of the loads in different types of electrical networks subjected to intentional electromagnetic interference (IEMI), are analysed with a method based on the Baum-Liu-Tesche (BLT) equation. The networks can be multi-conductor systems with multiple junctions and branches. To verify the calculation results, a commercial electromagnetic simulator based on elec...

In order to study the electromagnetic compatibility of a power system, authors adopted an effective analysis software and proposed a new prediction method. First, simulated and analyzed the electromagnetic transient when switching the no-load bus in the 500kV substation by the ATP software and proved the simulation results were consistent with the actual results; Second, introduced the Gray pre...

Thus, environmental monitoring is a crucial factor in the ecosystems health. Actually, methods for measuring salinity are mainly based on the mobility of ions in water (Zhao et al., 2003) changing the refractive index. However, these methods are inherently electrical and can be affected by any kind of electromagnetic interference. An alternative is the use of sensors based on optical technology...

We introduce an interferometric interpretation for the degree of polarization as a quantity characterizing the ability of a light beam to generate polarization modulation when it interferes with itself. The result is confirmed experimentally in Youngʼs interferometer with beams of controlled degree of polarization and by comparing to a standard polarimetric measurement. The new interpretation i...
