This book deals with the interaction between mobile telephone antenna and the human body. Where mobile telephones are typically used in close proximity to the head, significant levels of power can be absorbed. The primary effect is to cause local heating of the brain, and head tissue. This is of concern to some people who work continually with mobile telephones, and some form of "preventative" research should be done. This book presents: Brief review about the different numerical methods used to model electromagnetic problems Research work done by using the method of Auxiliary ...

This book deals with various sources of harmonics, the limit of IEEE-519 for both voltage and current, the effects of harmonics on various electric equipments. The book shows clearly the effects of harmonics on transformers. K-factor which is considered as a modern design for transformers to accommodate harmonic currents is investigated at different loading conditions. This book developed and discussed different cases, including harmonic voltage and current measurements on 11kV level, comparison of these values with the limit of IEEE-519, and calculation of K- factor for choosing the suitable...
