Abstract: This study presents a numerical analysis of the specific absorption rate in a head model exposed to electromagnetic fields when a real implant-retained prosthetic ear is attached to the side of the head. A set of dipole antennas operating at 900, 1800 and 2100 MHz were rotated to investigate the effect of frequency and polarisation. The maximum average 1 and 10 g specific absorption rates (SAR) have been presented to show the relative enhancement factor of the implant. A comparison of the mass-averaged SAR in the head with the implanted ear prosthesis shows that the 1 g SAR is doubled at 900 and 1800 MHz with different polarisations.
