This paper presents a procedure for the evaluation of the Electromagnetic (EM) interaction between the mobile phone antenna and human head, and investigates the factors may influence this interaction. These factors are considered for different mobile phone handset models operating in the GSM900, GSM1800/DCS, and UMTS/IMT-2000 bands, and next to head in cheek and tilt positions, in compliance wi...

This study analyzes the main parameters that should influence the specific absorption rate (SAR) in children's heads. The evolution of their head shape and the growth of specific parameters, such as the skull thickness, are analyzed. The influence of these parameters on the radio frequency (RF) exposure of children's head is studied. The SAR over 1 g in specific tissue is assessed in different ...

Communication between humans was first by sound through voice. With the desire for slightly more distance communication came, devices such as drums, then, visual methods such as signal flags and smoke signals were used. It has been only very recent in human history that the electromagnetic spectrum, outside the visible region, has been employed for communication, through the use of radio. One o...
