Complex Permeability and Composite Materials

The complex permeability and composite materials are made form Ni0,36Zn0,64 Fe2O4 ferrite material and the basic frequency characteristics and material properties will be presented in this article. The frequency range was measured up to 1GHz. We found the possibilities how to predict behaviour of these composites up that frequency. It was realized basically on complex permeability and mathematical model of these ferrite materials.
