000131139 5203_ $$aThis study aim is to investigate the ternary composites dielectric behavior and experimentally validate the predictive model that simplifies ternary models into binary ones using time domain spectroscopy (TDS). The scattered white silicon dioxide (SiO2) powder was evenly mixed with barium titanate (BaTiO3 or BT) powder in the same epoxy resin (RE) matrix. Over a frequency range from DC to 30 GHz, the dielectric behavior of these composite samples is examined, adding in particular a low frequency study at 500 MHz. The BT addition grew the mixture dielectric permittivity from 3.6063 to 8.2313 and moving the resonance frequency (ƒr) in the direction of the low frequency from 26.245 GHz until 17.09 GHz. By improving the shape factor smoothing and bringing theoretical and experimental results closer together, this seeks to optimize the modified Lichtenecker's law (MLL). These findings comparison demonstrates that the MLL model applies to ternary composites (RE-BT-SiO2) with an acceptable accuracy level. Another numerical method was used to evaluate the RE-[RE-BT-SiO2] composites employing a binary mixing model based on an MLL equation that is identical to the former ternary. This model results correlate well with binary composites experimental values as well as ternaries that are modeled using this law. This research perspective lies on the production of new materials for use in microelectronics and particularly on the MOS structure oxides improvement.
