| Abstract(in English) | Inside of closed areas surrounded by conductive walls, e.g., train carriages, airplanes or elevators, the RF wave transmitted from mobile phone creates a peculiar EMF distribution to the closed area different from in the free space. Since those areas are a part of the living environment, it is important to carefully assess the EMC safety issues related to the exposure guidelines and the implantable medical devices EMI. However, it is not easy to correctly analyze EMF distribution and estimate SARs or EMIs regarding internal human body for microwave RF waves due to the analysis model complexity. An assumption of approximated loss free condition ignoring the existence of human bodies causes fatal over estimations [1]. Hence, it is necessary for accurate analyses and estimations to include the human bodies of mobile phone user and other passengers in modeling. This special lecture summarizes the study results of precise numerical simulations of EMF[2], experimental measurements[2], an EMF approximation based on an ultimate endless reflection hypothesis[3], and EMC evaluations on human body[2],[4] which this lecturer directed concerning some typical closed areas, and related social issues. |
