Numerical Estimation of Electric Field Distribution in Wireless Office LANs Using the FDTD Method

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.
