Analysis of passive electromagnetic exposure to multisource distributed in outdoor places

Abstract

In this paper an analysis of the electromagnetic fields (EMF) produced by dipole antennas located near a passive user is presented. A passive user is understood to be a subscriber that is not accessing a wireless device while it is exposed to radiation. The model adopted for the human head consists of four concentric geoid layers of human tissue. For the worst case of electric coupling, which in a real case represents the hot spot in the human head, spatial arrangements of up to three antennas are obtained using a genetic algorithm. For the simulations, horizontally polarized antennas are placed at a fixed distance from the head. Results for the maximum EMF levels on a passive user are presented. The levels obtained are compared to ICNIRP and ANATEL's reference levels.
