Background: In recent years, the widespread use of microwave producing instruments specially mobile phones; result in growing concern regarding the possible effects associated with these waves on human health. Some studies highlight the possible health hazards of electromagnetic fields (EMF), while others contest the hypothesis of biological impact of EMF. The aim of this study was to evaluate ...

This paper provides an alternative and highly accurate method in predicting Small Signal Performance of Microwave Amplifier. An Electromagnetic (EM) simulator that based on Finite Element Method (FEM) was used in combination with the conventional SPICE-based microwave circuit simulator in order to demonstrate the superiority in performance outcome such as Rollet Stability Factor (K), Return Los...

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...

Background: The use of mobile phone by children is increasing drastically. Children are likely to accumulate many years of exposure during their lives. Furthermore, as nervous systems in children are developing, children may be at a greater risk compared to adults. In this light, some scientists have suggested that the use of mobile phones should be restricted in high-risk groups such as childr...

Public concerns over possible adverse effects of microwave radiation emitted by mobile phones on health are increasing. To evaluate the intensity of oxidative stress, cognitive impairment and inflammation in brain of Fischer rats exposed to microwave radiation, male Fischer-344 rats were exposed to 900 MHz microwave radiation (SAR = 5.953 x 10(-4) W/kg) and 1800 MHz microwave radiation (SAR = 5...

To investigate the effect of microwave emitted by mobile phones on the rat central nervous system (CNS), in vitro cultured cortical neuronal cells and in vivo rat’s brain were exposed to the electromagnetic waves emitted by a microwave transmitter that mimics the working frequency of mobile phones. Trypan blue staining and terminal deoxynucleotidy transferase-mediated dUTP nick-end labeling (TU...

The Sky Net project proposes a mobile base transceiver station (BTS) for mobile communication service from airborne. In the preliminary study, a Microwave AirBridging (MAB) system is established on an Ultra-Light Aircraft (ULA) to offer relay mobile communication. In order to maintain sufficient Quality of Service (QoS) data-link, microwave system needs to establish critical Line-of-Sight (LoS)...

Mobile phone radiation and health concerns have been raised, especially following the enormous increase in the use of wireless mobile telephony throughout the world (as of August 2005, there were more than 2 billion users worldwide). This is because mobile phones use electromagnetic waves in the microwave range. These concerns have induced a large body of research (both epidemiological and expe...

The aim of the present work is to evaluate possibility of microwave emitted by cellular phone that can elicit cortical spreading depression (CSD) in rat brain and studying the characteristics of the evoked signals. (CSD) was elicited in cerebral cortex of anesthetized rats after exposure to microwave irradiation (935.2-960.2 MHz) from Global System for Mobile communications (GSM) mobile phone. ...
