Abstract

We present the results of an exposure assessment study in terms of whole-body specific absorption rate due to radio frequency electromagnetic fields exposure inside a loaded reverberant environment. The approach is based on the reverberation chamber theory. Previous studies have considered only the scenario of a single exposed object inside the chamber. Here we study more realistic scenarios where, in addition to an exposed object, there are also other lossy objects present inside the chamber. The additional lossy objects essentially introduce additional load to the chamber. The approach used in this study relies on the chamber’s Q factor and the absorption cross section of the loading objects. We show that exposure strongly depends on the chamber properties and its loading.
