Advanced Temperature Dielectric Spectroscopy Of Muscle Phantom At Microwave Frequencies

Abstract

The temperature dependency of the dielectric properties of tissues is very important for the development of novel microwave systems intended for non-invasive temperature monitoring. This paper deals with the measurement and optimization of the temperature dependence of the dielectric parameters of a muscle tissue mimicking phantom. The measurements were performed in the frequency band 0.1-3 GHz and in the temperature range 25-45 °C. The differences in the dielectric parameters caused by temperature change were analyzed and compared with the reference.
