Executive Summary

The purpose of this study is to develop accurate and reliable estimation method of Electromagnetic field distributions in practical environments including humans absorption effects. In this paper, large-scale numerical simulations are carried out to examine the electromagnetic fields excited by the wireless LAN terminal inside an office. The author used a typical office model and employed the FDTD technique and a supercomputer to estimate the field distributions inside the whole area of the room. Furthermore, a simplified histogram estimation method for electric field strength was employed to deal with the complicated EMF distributions inside the office.
