Abstract
Depending on the desired performances of ferrites, their microwave characteristics must be optimized. Ferrite elaboration relies on highly reproducible compositions and microstructures. In order to fulfil these requirements, manufacturers have to control all the different processing parameters. The selection of the compositional gradation as well as the manufacturing procedure, require accurate and reliable microwave measurement data. A special process has therefore been developed for complex permittivity and permeability measurements. Closely related compositions of ferrites can thus be distinguished and experimental data can be interpreted on the basis of theoretical models.
