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...

Mobile phones are two-way radios that emit electromagnetic radiation in microwave range. As the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. As self-monitoring of blood glucose can be a beneficial part of diabetes control, ho...

The main purpose of the paper is to present the impact of the polarization state of light in fiber optic interference sensors on their stability and efficiency. The main application of interference-based sensors for security is the protection of wide area objects, especially perimeter protection. This type of sensor offers high accuracy of locating disturbances and a high certainty of detection...

Mobile telephone systems divide the coverage area among low transmitting power sectors. This allows the so-called frequency reuse between sectors: geographically “distant” sectors might employ the same electromagnetic frequencies, since the probability of interference between them is small. The electromagnetic frequencies available for mobile communications are very limited and their use is reg...

The duality found by Aharonov and Casher for topological phases in the electromagnetic field is generalized to an arbitrary linear interaction. This provides a heuristic principle for obtaining a new solution of the field equations from a known solution. This is applied to the general relativistic Sagnac phase shift due to the gravitational field in the interference of mass or energy around a l...

This paper presents the Electromagnetic interference (EMI) and Electromagnetic compatibility (EMC) analysis of a Printed Circuit Board (PCB). The width of the differential pair trace of the PCB was varied and the emission values were measured and compared, demonstrating an improvement in radiated emissions when the width of the trace was decreased. The trace width of the PCB was increased from ...

In order to extract the millivolt range partial discharge(PD) signals drown in the harsh electromagnetic interference for HV power cables, this paper presents a novel antiinterference method, based on fast fourier transform autothresholding method, 1-D discrete wavelet thresholding method and three phase amplitude and arrive-time difference method. This method is examined and proved to be effec...

The paper deals with the immunity to Electromagnetic Interference (EMI) of current source for Ultra-Low-Voltage Integrated Circuits (ICs). Based on properties IC building blocks, such as current-splitter and correlator, a novel generator is conceived. proposed solution suitable provide currents ICs operating in sub-threshold region even presence an electromagnetic polluted environment. EMI comp...

this paper presents a novel control approach used in shunt active power filter based on variable structure control combined with random pwm technique (rvsc) that provides robust, fast, and more favorable performance for active power filter. this control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

The transmission line matrix time domain (TLM-TD) method is used to simulate the electromagnetic pulse (EMP) coupled inside a shielding box with an aperture. Simulations for different electromagnetic pulses regarding to different rise time and fall time have been performed. The results for shielding effectiveness of these different excitations have been presented. A simple method that uses an e...
