physical agents such as ultraviolet or ionizing radiation and repetitive trauma have been related to the causation of cancer in humans. much less clear is the association between exposure to radiofrequency, such as radar and microwave radiation to the development of cancer. sporadic case reports and small series suggest that this type of radiation might lead to cancer or contribute to its evolu...

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...

voltages and currents are induced into electronic circuit boards as electromagnetic waves are radiated on them. the strength of induction depends on the wavefront and the circuit board characteristics. in this paper, by solving maxwell’s equations using fdtd method and then by extending it by three dimensional simulation using the gpml criteria for boundary conditions and tf/sf technique, effec...

As organisms exposed to various abiotic and biotic environmental impacts, plants are able to recognize and respond to their surrounding environment with high specificity. Electromagnetic field radiation is an important effective stress factor on growth and development of plants. Our research focused on plants grown from wet pretreated seeds with low frequency electromagnetic field exposure comp...

This paper presents the electromagnetic interference and electromagnetic susceptibility characteristics of the railway telecommunication intra-subsystem. These are for assessing the electromagnetic compatibility inside the railway telecommunication subsystem and providing input data for electromagnetic compatibility analysis of other subsystems (intra-system analysis). This paper shows the opti...
