|Title||The Effect of Sector Antennas on Human Head Model in Term of Electromagnetic Radiation and SAR Distribution|
The rapid diffusion of wireless communication systems such as cellular phones and wireless local area networks has caused an increased concern for the potential detrimental effect on human health deriving from exposure to EM fields emitted by the antennas of these systems. In particular, with reference to cellular telecommunication systems, two different exposure condition are present. The first is the exposure of the user's head to the portable phone and the second is the general population exposure to the field radiated by the base station antennas, the researcher in this study will discuss the general population exposure to the field radiated by the base station antennas. In this study, the exposure of an anatomical model of the human head represented by (skin-bone-brain) to the field radiated by a base station antenna operating around 900MHz has been studied by using the matlab program and FDTD technique. Numerical method such as FDTD method has been used to study theoretically the biological effect of electromagnetic waves produced from mobile phone base station on human head life tissue. Specific Absorption Rate(SAR) ,electric and magnetic field has been drawn with respect to time steps; according to this study the SAR in skin and bone is higher than in other tissue.
