Wide range dielectric behavior characterization of ternary composite (Re-BT-CaO)

This article's primary objective is to investigate a ternary composite's dielectric behavior using time domain spectroscopy (TDS). A heterogeneous mixture of barium titanate (BT) and calcium oxide (CaO) in an epoxy resin matrix (RE) with a predetermined volume fraction level (70%) makes up this type of material. The remaining components (BT and CaO) are variable in increments of 07.50% and complete one another in order to achieve the final percentage, which is 30%. The different composite samples are created using the aforementioned stoichiometric ratios at room temperature and below atmospheric pressure. These mixes are put through a dielectric behavior analysis over a broad frequency range, from DC to 10 GHz. This study intends to highlight the impact of calcium oxide and barium titanate on the composite's dielectric behavior and on the form factor provided by the modified Lichtenecker equation (MLL). It follows a numerical method for optimizing of the predictive model of this law based on a better smoothing of this shape factor in order to allow a better concordance among the predicted values and practical ones. A comparison between the experimental data and the MLL values is performed in order to highlight the proposed model performance on the ternary composite dielectric permittivity estimation quality. This research's focus is on how these materials are used in micro- and nanoelectronics as well as telecommunication components fabrication.
