As an object of investigations BiNbO4-based microwave ceramics was taken. Simulations of the hypothetical impedance response of the ceramic system were performed under assumption of the brick-layer model. A strategy for analysis and modelling of the impedance data for microwave electroceramics was discussed. On the base of the discussed strategy modelling of the dielectric response of BiNbO4 ceramics was performed with the electric equivalent circuit method. The Voigt’s and Maxwell’s circuits were taken as electric models. Parameters of the electric components of the circuits were determined and related to parameters of the ceramic object under study. It was found that fitting quality was good and changed within the range χ2 = 6.78 × 10–4 – 6.77 × 10–5 depending on the model.}, type={Article}, title={Modelling of Dielectric Properties of BiNbO4-Based Microwave Ceramics}, URL={http://journals.pan.pl/Content/116401/PDF/AMM-2020-3-34-Czekaj.pdf}, doi={10.24425/amm.2020.133236}, keywords={BiNbO4 ceramics, impedance spectroscopy, simulation and modelling, equivalent electric circuit method}, }
