a time-domain approach is presented to calculate electromagnetic fields inside a large electromagnetic pulse (emp) simulator. this type of emp simulator is used for studying the effect of electromagnetic pulses on electrical apparatus in various structures such as vehicles, a reoplanes, etc. the simulator consists of three planar transmission lines. to solve the problem, we first model the meta...

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...

Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called electromagnetic radiation because they radiate from the electrically charged particles. They travel through empty space as well as through air and other substances. Electromagnetic waves at low frequencies are referred to as electromagnetic fields and those at very high frequencies ar...

today, there is an increasing interest in the use of metal nanoparticles in health sciences. amongst all nanoparticles, the gold nanoparticles have been known to kill the cancer cells under hyperthermic condition by near-infrared frequency electromagnetic waves. on the other hand, although there are different physiochemical methods for disinfection of microbial pollution, however applications o...
