Abstract: The electric field dependence on the dielectric properties of the porous ceramics was studied theoretically. The dielectric constant of the porous ceramics under certain direct current (dc) bias field and the real strength electric field in the porous ceramics were given quantitatively. As the pore can share the electric field, the tunability of the porous ceramics will be decreased when the porosity increases. The dielectric constant evolution of Ba₀.₆Sr₀.₄TiO₃-based porous ceramics with the dc bias electric field can be successfully explained by our theoretical results. Taking Ba₀.₆Sr₀.₄TiO₃-based porous ceramic samples, for example, there is good correspondence between the theoretical and the experimental results.
