In the present work, microwave dielectric properties of biphase ceramics were calculated via finite element method (FEM) combined with Monte Carlo (MC) simulation. Parameters such as volume fractions, and dielectric constant ratio of two phases were taken into account. Random distribution of tow phases was generated by MC method. Both dielectric constant and Qf values were calculated and then numerical fittings were carried out. The simulation results of the dielectric constant were then compared with experiment data and excellent agreement was achieved.
