Influence of Measured Dielectric Properties to SAR Values

To investigate dependance of SAR on dielectric properties of liquids simulating human tissue, we have mixed liquids using different percentage of NaCl, sugar and water to acquire values of permittivity and conductivity recommended by the CENELEC norm 50361. Measurements of electric field for the frequency range from 400 to 2900 MHz using three-axes isotropic electric field probe and a three axes positioner have been performed. We calculated SAR values from these measurements and found interrelationship between variations of SARs and permittivity.
