Some microwave passive components (such as circulators, isolators, ... etc) still use bulk magnetic materials. A method for the dielectric and magnetic characterization of multi-layer materials in the microwave range is presented as well as its reliability and its domain of validity. It allows to determine the elements of the permeability tensor of gyromagnetic slab. This method of material characterization can be implemented at various microwave bands by changing the geometrical dimensions of the rectangular waveguide.
