Abstract

The complex permittivity, complex permeability and electromagnetic interference (EMI) shielding properties of the BaTiO₃ ceramic filled with NiFe₂O₄ micron-grade particle or nanoparticles were investigated. As the micron-grade NiFe₂O₄ particles decreased to about 30 nm, NiFe₂O₄ nanoparticles filled BaTiO₃ ceramics with high complex permittivity can be obtained in the X–band. The total EMI shielding effectiveness of 30 wt% NiFe₂O₄ nanoparticles filled BaTiO₃ ceramics is greater than 34 dB with a thickness of 1.2 mm. The results of this experiments demonstrated that such ceramics can be used to produce high complex permittivity materials for high-performance EMI shielding applications.
