Comparative study between Lichtenecker Modified Model and Bottreau’s Law for two binary composites (RE-BT) and (RE-SiO2)

The aim of this communication is to compare two proposed mixture laws (The Lichtenecker Modified Model and Bottreau’s Law) with experimental results in order to determine which law best describes the dielectric behavior of binary mixtures. To achieve this, we have analyzed the dielectric permittivity behavior of binary composites composed of two different combinations: Epoxy Resin (RE) with Silicon dioxide $\left(\mathrm{SiO}_{2}\right)$ and Epoxy Resin (RE) with Barium Titanate (BT), considering variations in frequency and the volume fraction of the fillers.
