MULTIPLE MULTIPOLE METHOD APPLIED TO AN EXPOSURE SAFETY STUDY

Abstract

A summary of the three-dimensional implementation of the multiple multipole method (3D MMlP) is given, followed by discussions on the method's advantage and limitations on the basis of an example study. The advantages are seen in its quantitative validation capability, in its efficiency for smoothly shaped bodies and its achievable accuracy, in particular, near surfaces. However, MMP's greatest strength appears to be with problems with EM sources in the closest vicinity of lossy bodies. This is shown by a condensed presentation of a study investigating the RF exposure safety of UHF and VHF transmitters commonly used by radio and TV crews for onsite live reports. In addition to gaining knowledge about the locar SAR distribution, the goal of this study was to assess necessary safety distances for given threshold values. The presented study was performed with the 3D MMP software package on a 80386 based PC laptop extended by a 80860 board with 32MB RAM.
