Sažetak
In this study, we provide a novel approach for exposure assessment in terms of whole-body average specific absorption rate (WBSAR) due to the electromagnetic fields inside reverberant environments. The approach utilizes power balance theory and the lossy object’s absorption cross section (ACS).We use this to present a noninvasive technique for determining the WBSAR in reflective environments. Measurements were performed inside a reverberation chamber on spherically-shaped phantoms filled with lossy liquids. The approach was verified by performing invasive temperature measurements and showed excellent agreement (within 5%). This approach can be used for human exposure assessment inside reverberant environments since human body ACS has been well studied in the literature. The main advantage of the proposed approach is that it overcomes the need for complex invasive measurements in order to determine WBSAR.
