N2 - This paper investigates the effects of metallic jewellery on the SAR in progressively more complex models of the human head, using the FDTD method. A half-wavelength dipole excitation at 1800MHz is positioned in front of the head to represent a cellular enabled personal communication device. FDTD results show good agreement with DASY4 measurements. Metallic jewellery has been found to increase SAR in the head and the levels of SAR depends on the shape and the electrical properties of the tissues in the head. A metallic pin was found to increase the SAR averaged over Ig by 16.0 times in a homogeneous cubic head, whereas, the same pin increased the Ig SAR in an anatomically realistic head by a factor of only 2.5. The results shown in this paper are for a metallic pin that may represent a facial piercing, a section of metallic spectacles or a microphone for a hands free kit.
