Measuring and Analyzing the SAR Inclination in Human Exposure

Jacob Abharam, P. Vipeesh

Abstract


This paper makes an attempt to study and analyze the various operating parameters which influence the SAR measurements. The experimental evaluations are done in the radiative near field area covering a distance between 30 – 50 m depending upon the operating frequency. This paper tries to locate a suitable frequency whose SAR will be minimum. According to international standards the key parameters that influence SAR include distance, frequency phone angle, Tissue type and the Age.

Keywords


Mobile Phone, Specific Absorption Rate, Electromagnetic Fields, Radiative Near Field, FDTD.
