Indicative SAR levels due to an active mobile phone in a front trouser pocket in proximity to common metallic objects

This paper investigates Specific Absorption Rates (SAR) in the human body with a realistic mobile phone source positioned in a ‘front trouser pocket’ of a truncated male heterogeneous anatomical body model. A Finite-Difference Time-Domain (FDTD) code was used to analyse the SAR in the body in the mobile communication frequency range 0.9 to 4GHz. Realistic everyday metallic objects, including a coin, a ring and a zip were added to the model. These objects increased the SAR in the body at different frequencies. The cumulative effect of the three objects generally increased the SAR in the waist section over the frequency range considered.
