Abstract
The results about the measurements of complex permittivity of hydraulic mineral oil is here presented. Two different oil samples were analyzed using this method: a non-used one and a sample with 1000 hours of usage. The obtained data were collected by using the cavity perturbation technique exploiting a coaxial cavity resonator. To overcame the approximations that are usually made in this technique a particular measurement procedure based on 3D-full wave electromagnetic simulations has been performed.
