High power electromagnetic pulse applicators for evaluation of biological effects induced by electromagnetic radiation waves

Fabrication of High Frequency Electromagnetic Waves Absorber Sheets by Use of Iron Oxide Nanostructures

 Background & Objective: The necessity of using wireless communications and the use of electromagnetic waves in today's world is obvious to everyone. Using of these equipment and development of them, although have many benefits but causes some anxiety on the way in which they influence on environment. One of the most effective ways of decreasing the unwanted effects of these waves is using of t...

Electromagnetic field induced biological effects in humans.

Exposure to artificial radio frequency electromagnetic fields (EMFs) has increased significantly in recent decades. Therefore, there is a growing scientific and social interest in its influence on health, even upon exposure significantly below the applicable standards. The intensity of electromagnetic radiation in human environment is increasing and currently reaches astronomical levels that ha...

Electromagnetic radiation induced by a gravitational wave

Biological effects of electromagnetic fields.

Life on earth has evolved in a sea of natural electromagnetic (EM) fields. Over the past century, this natural environment has sharply changed with introduction of a vast and growing spectrum of man-made EM fields. From models based on equilibrium thermodynamics and thermal effects, these fields were initially considered too weak to interact with biomolecular systems, and thus incapable of infl...

Characterization of Power Transformer Electromagnetic Forces Affected by Winding Faults

Electromagnetic forces in power transformer windings are produced by interaction between the leakage fluxes and current passing them. Since the leakage flux distribution along the windings height is in two axial and radial directions, so the electromagnetic forces have two components, radial and axial. There is a risk that a large electromagnetic force due to the short circuit or inrush current...
