“…18 A change in impedance in the propagation medium will cause any reflection in the line. 19 The analysis of the reflection coefficient will then make it possible to determine the desired electromagnetic parameters, depending on the nature of the material to be characterized. 20 The variations of the complex permittivity as a function of the frequency are obtained after discrete Fourier transform (DFT) of both incident and reflected signals of this material's sample.…”

In the same matrix of epoxy resin, Fe3O4 powder was evenly mixed with one of two titanate powders, CaTiO3 or SrTiO3. The dielectric properties of these blends were evaluated using the measurement technique of time domain spectroscopy. During this work, low-frequency analyses (DC - 300 MHz) were carried out, mainly focusing on the static permittivity and conductivity properties as a function of titanate concentrations. The results allowed us to confirm the validity and effectiveness of the modified Lichtenecker Laws (MLL). Significant agreement can be shown between the MLL-calculated and experimentally determined permittivity values for ternary combinations. The perspective of this research lies in the production of new materials for use in the field of telecommunications and in particular for microelectronic components.
