This work presents the dielectric properties of different mixtures of distilled water and ethylene glycol in the frequency range 0.5-8 GHz and at 25 °C. The measured dielectric properties are fitted to Debye and Davidson-Cole relaxation models depending on the percentage of ethylene glycol in the mixtures. The relationship between model parameter values and mixture types are found. Dielectric properties of mixtures at 2.45 GHz are compared with those of high-loss tissues and tumors found in literature suggesting them to be used as liquid phantoms.
