Usually, knowledge of material's dielectric properties, as a function of frequency, represents a key issue in scienti c elds and several industrial applications. At LNE-CETIAT, in partnership with Institut Fresnel UMR 72792, a set of capacitive and coaxial cells, dedicated to the measurement of complex dielectric permittivity, have been developed. The present paper focuses on the experimental calibration and validation of two cells using low and medium dielectric loss materials. It gives the main measurement results obtained on three di erent materials: decanol alcohol, polytetra uoroethylene (PTFE) and polyvinyl chloride (PVC) in the frequency range from 3 MHz up to 2 GHz.
