Characterization of Binary Composite Made of Epoxy Resin and Barium Titanate in High Frequency Range

In this work we study the dielectric behavior of a binary composite, barium titanate (BaTiO3) and epoxy resin (RE) which is used as a matrix; the characterization of the mixture is done by time-domain spectroscopy (TDS) in a frequency range between DC and 10GHz. The composites are mixed at room temperature and under atmospheric pressure. In order to see the influence of BaTiO3 over the epoxy resin, we made different combinations. The experimental results are compared to the Lichtenecker modified Law; this model gives a good concordance with the experimental curve and it is situated between the two limits of Wiener Laws (upper and lower). This confirms the efficiency of MLL model in predicting the behavior of binary mixture. The importance of this study appears in the application of these composites in developing components in the telecommunication field.
