Dielectric characterization of alcoholic beverages and solutions of ethanol in water under microwave radiation in the 1-20Â GHz range

We measured the dielectric permittivity of several solutions of ethyl alcohol in water and observed that their spectra follow the Debye model. The parameters used to adjust the Debye model according to the alcohol concentration in a solution follow a linear law. We tested the resulting model with various alcoholic beverages and found that we can obtain the concentration of alcoholic solutions using our model.
