Abstract

Age-dependent dielectric properties of tissues have been calculated based on a number of interpolation equations in the frequency range of 0.4-10GHz. The proposed method for calculating age-dependent dielectric properties is based on mapping the existing measured data [1] for pigs to those of humans using weight/age plots. The method provides growth curves relating the dielectric properties of both species for specified ages. The new age dependant dielectric data is then used in numerically discretised human models to assess the Specific Absorption Rates (SARs) induced when the models are exposed to a plane wave at 0.4GHz and 1GHz respectively. Comparisons were carried out between the models using the legacy tissue data, and those with age related dielectric data. As a result of this replacement, increase of approximately 3% and 24% were observed at 0.4 and 1GHz respectively, for the peak SAR in the adult models.
