Human exposure study for large scale scenarios

This paper presents the human exposure simulation study considering the presence of a hand, holding the handset, and some resonant effects due to the presence of the room walls. The motivation for this research is the necessity to consider influence of the hand on the field in the near zone for proper understanding of the exposure nature. It is known that for some frequencies rooms in the ferroconcrete buildings are resonant for EM field. The standing waves may be created with field values several times higher than value of the incident field. One of the parameters to consider for resonant effects study is the variable wall transparency. We have investigated several cases when a human with a cell phone is located inside and outside of a room and also the case when the EM source is the base station antenna. The problem is solved using the Method of Auxiliary Sources with a user friendly program package, created for numerical experiments for this particular problem. Several cases of the human location and building wall's transparency parameters are considered during the calculations. The numerical experiment results are presented and analyzed.
