Abstract

The effects of the radio frequency human exposure to mobile phone, inside both partially and fully enclosed metallic elevators, have been analyzed. It has been found that the evaluated peak Specific Absorption Rate (SAR) and the whole body absorption power are increased only by a small percentage inside the partial enclosures as compared to the free space environment; whereas inside the full enclosure, the peak SAR and the whole body absorption power are significantly increased. The analysis suggest that the reason of such a high level of RF energy absorption inside a fully enclosed metallic elevator is mainly because of the resonance effect.

Main findings

The analysis found that peak SAR and whole-body absorption power increased only by a small percentage in partially enclosed metallic elevators compared with free space. In fully enclosed metallic elevators, peak SAR and whole-body absorption power were significantly increased, which the authors attributed mainly to resonance effects.
