Near fields radiation superposition assessment in human nearby users of cellular phones

This paper deals with the field superposition assessment closer to the human head by mapping the region around it when various mobile phones are in operation. The electromagnetic simulation is based on the CST MICROWAVE STUDIO^® (CST MWS). In this work, the model of the human head considers concentric dielectric spheres with various electrical permittivities. This paper highlights the well known existence of electric fields in regions nearby the active users of cellular phones and, particularly, around the passive users closed to them. The simulated results for the electromagnetic field behaviour change around the passive users in the presence of more than one cellular phone users (active user) are presented.
