Numerical analysis of electromagnetic field distributions in a typical aircraft

DOI

説明

The purpose of this study is to develop accurate and reliable estimation method of Electromagnetic field distributions in practical environments including passengers. However, comprehensive measurements in an actual environment cost too much and it is difficult to carry them out precisely. In this paper, large-scale numerical simulations are carried out to examine the electromagnetic fields excited by the 2.45 GHz wireless LAN terminal inside an aircraft. We used a typical aircraft model and employed the FDTD technique and a supercomputer to estimate the field distributions inside the whole area of the cabin. A Large-scale parallel computing technique based upon several node partitions of a supercomputer was used because of its memory and speed capabilities. It is able to give us a good perspective within a reasonable computation time. Furthermore, a simplified histogram estimation method for electric field strength in the cabin was employed to deal with the complicated EMF distributions inside the cabin including passengers.
