This Paper proposes a pragmatic approach to determine and analyze the effects of radio frequency on human exposure. A scenario in which a Mobile Phone is used inside a partially closed elevator and fully closed Elevators is considered. Elevators are metallic enclosures but still 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 examines and compares the levels of absorption in terms of SAR values under various conditions. In this paper a human phantom with dielectric properties is designed and its interaction is studied with IFA under three conditions free space, elevators in partially closed and full closed conditions. The results shows that SAR computation and its value seems to be increased in partially closed elevator and greatly in fully closed elevators as compared to free space. The method of computation uses MOM. Simulations are done by FEKO software.
