Abstract

In this paper we present some results concerning the study of mixed dielectrics; two types of materials were studied: a compound of titanate and epoxy resin and mixtures of pentanol-cyclohexane in different concentrations. For the measurement of permittivity the Time Domain Reflectometry (TDR) method was used; this method enables to determine the reflection coefficient and next by applying a Fourier transformation one obtains the complex dielectric permittivity in a large range of frequencies..
