Electromagnetic Characteristics Measurement Setup at Variable Temperatures Using a Coaxial Cell

Figure 5

(a) Graphic representing the real part of permittivity of a sample of octanol with a positive and negative slope of temperature variation. (b) Graphic representing the real part of permittivity of ethanol at 100 MHz as a function of time. It shows a heating-up process where at the beginning, the temperature was 30°C and after 600s, 35°C.
