This research is focused on the effect of various incident angles of the linear polarized electromagnetic exposure from mobile phone to the value of Specific Absorption Rate (SAR) in human head which is a safety standardization for mobile phone user. Method of Moment is chosen to calculate the electric field in the human head because it is the most suitable method. The incident electromagnetic is assumed as a plane wave with a frequency at 900 MHz and power density of antenna for 4.5 W/m 2 • The integral used for calculation is Tensor Integral Equation (TIE). Human head is modelled as a homogeneous spheroid and is divided into cubical cells. The incident angles which are examined are 0° (horizontal polarization), 15°, 30°, 45°,6 0°, 75°and 90° (vertical polarization). The results show that the incident angle does not affect the average SAR in the human head, but it affects the local and maximum SAR of the cells in human head. The difference of seven angles maximum SAR does not vary in the form of linear but in the form of damped sinusoidal. The angle which produces the least maximum SAR is 0° namely 0.1521 W/kg whereas the angle which produces the highest maximum SAR is produced by angle 15°namely 0.1748 W /kg. The highest SAR is obtained around the side of the head near the electromagnetic exposure source. None of the SAR produced by the variation of incident angle is above the limit of safety standard.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
