Electromagnetic Radiation from a Tesla Transformer

Electromagnetic radiation from bound electrons

Electromagnetic radiation from microwave ovens.

Electromagnetic radiation from microwave ovens in Saudi Arabia was investigated by means of a field measurement survey. The survey was carried out for 106 ovens used in households and restaurants in Riyadh city. Ovens were between 1 month and 14 years old with operating power ranging from 0.5 to 4.4 kW. One oven was found to leak more than the 5 mW cm(-2) limit specified in the standard. Fiftee...

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...

Polarized electromagnetic radiation from spatially correlated sources.

We consider the effect of spatial correlations in sources of polarized electromagnetic radiation. We evaluate the coherency matrix for a spatially extended three-dimensional source in order to obtain its dependence on the angular position of the observer in the far zone. We find a general condition on the source correlation matrix under which the polarization in the far zone shows no angular de...

Risks of Carcinogenesis from Electromagnetic Radiation

Apparently, any technical device was not introduced in everyday human life so fast and so close as mobile phone. Starting from first commercial mobile phone network in Japan in 1979 the number of active users of mobile telephony increased to over 3 billion all over the world. In developed countries the number of mobile phone users today is close to saturation. The initial age of youngest users ...
