| Popis: | In this paper, radiometry measurements of human tissue layer phantom temperature are presented. A skin-fat-muscle phantom allows independent heating/cooling of the lowest muscle layer. A narrowband probe is designed specifically for that tissue stack-up and a sensitive radiometer is used to measure total radiometric power in the 1.4-GHz quiet band. The knowledge of the volume power loss density from the probe, obtained from full-wave simulations, is used to determine the tissue weighting functions, which in turn allows for estimating black-body power radiated from a specific buried layer. Measured data using a Dicke radiometer shows that the radiometer tracks the internal tissue temperature. |
