This Paper proposes a realistic approach to determine and analyze the effects of radio frequency on human exposure in presence of a metal slab. A scenario in which a Mobile Phone is used in presence of metal slab which is perfect electric conductor considered. Metal slabs are known to have resonance and reflection effects, thereby increasing electric field strength and resulting in change in levels of human exposure to Electromagnetic absorptions. So this paper compares the levels of absorption in terms of SAR values. In this paper a human phantom with dielectric properties is designed and its interaction is studied with IFA antennas under two conditions free space and in presence of the metal slab. The results are obtained and SAR is computed and its value seems to be increased in presence of the metal slab compared to free space. The method of computation uses MOM and this is enabled by FEKO software.
