Abstract

This paper presents an assessment of radiation electromagnetic (EM) energy absorption by using far-field measurement system. Dipole radiator was applied for closed proximate Specific Anthropomorphic Mannequin (SAM) in order to measure EM energy, radiation pattern and Specific Absorption Rate (SAR). The evaluation of SAR values were taken from numerical analysis and experimental measurement. In this study, scattering and power absorption of SAM were evaluated by environmental measurement. To simplify the computational complication, uniform similar tissue liquids were used in this study for evaluation of EM radiation energy. The concept of Poynting vector was applied to derivate the degree of human head damage subjected to EM radiation energy that may be evaluated with the far-field.
