| Abstract(in English) | The purpose of this study is to estimate the Electromagnetic field (EMF) distributions emitted by cellular radios in environments surrounded by conductive surfaces, e.g., train carriages or elevators. In this paper, we discuss the effect of a passenger's absorption of electromagnetic fields inside the elevator in more detail. We have proposed a numerical estimation method based on the FDTD technique to examine the EMF in actual elevators. Also an electric field histogram estimation method for electric field strength has been developed to deal with the complicated EMF distributions. This made it possible to estimate the EMI risk to pacemakers by cellular radio transmission quantitatively. As a result, we have stated that the effects of losses due to the human body could not be disregarded for the estimation in the actual environment. |
