In today’s lifestyle it is unthinkable to have a day without coming into contact with electronic devices such as cell phones, laptops, tablets, Televisions and now LEDs. In the whole world people are relying heavily on these technological tools for entertainment and for communication with friends, family, and at school and work. All these devices emit Electro-Magnetic Radiations (EMR) which are harmful for human beings as they cause many harmful effects including Cancer. Data gathered from 13 participating countries was pooled and analyzed by the International Agency for Research on Cancer (IA

Mobile telephony is not very old phenomenon, it functions based on electro-magnetic-radiation (EMR). Mobile telephony has eased the communication. Almost ninety percent work are done using mobile telephony. Therefore, use and users of mobile telephony are increasing rapidly and significantly daily. Recently, some published research studies show that mobile telephony affects the human health and reproductive system too. Percentage of cancer and tumor cases have also enhanced significantly all over the world. In animal it is well established that electro-magnetic radiation (EMR) affects male rep

Grinding in a high-energy planetary mill for up to 60 minutes made it possible to obtain hexaferrite powder particles with the average size successively decreasing from 1.5–2 μm to 0.05–0.15 μm. A scanning electron microscope was used for the analysis. Samples were prepared in a mixture with a polymer binder (70% ferrite + 30% polymer), and their electromagnetic radiation (EMR) absorbing cap

The effects of electric field and/or magnetic field on the rheological property of iron suspension were studied by use of parallel-plate rheometers developed for electro-magnetorheological (EMR) measurements. The EMR effect, which is defined as an increase in the shear stress under combined fields, was dependent on the strength and direction of the fields. In particular, significant synergism was found in the EMR effect when the electric and magnetic fields were applied in parallel. Observation of the suspensions solidified in parallel field and crossed field conditions revealed different stru

Genotoxic Effects of Radiofrequency-Electromagnetic Fields.
 IntroductionRadiation is energy emission in the form of electromagnetic waves emitted from the solar system and natural resources on earth. The currents produced by the elementary particles formed by the electric current create the magnetic field. Earth's surface is under the influence of the geomagnetic field emanating from the sun. However, the outer liquid also has a magnetic field created as a result of heat transfer in the core. Therefore, all living organisms on earth live under the influence of electromagnetic fields (EMF

Internal WPE problems are solved using waveguide modal expansion in the port plane, while external problems are solved using the equivalence principle to reduce these problems to
