Effect of the electromagnetic properties of equivalent liquid on the radiating antenna matching for SAR measurements

Dominique Picard

Résumé

The SAR measurements are realized by means of a human body phantom filled with a liquid the dielectric properties of which are the ones of the biological tissues. The errors on the values of the 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 first aspect which modifies the value of the emitted power and consequently the value of the SAR.
