SAR measurements probe sensitivity function of the dielectric properties of the tissue equivalent liquid

International audienceThe dielectric properties of the biological tissue equivalent liquid are a cause of error on SAR measurements. Three different parameters are modified by the dielectric properties of the tissue equivalent liquid: 1) the adaptation of the radiating antenna, 2) the coupling between this antenna and the liquid and 3) the sensitivity of the probe in the liquid. This study is devoted to the third aspect for the GSM900 and GSM1800 frequency bands
