The electromagnetic properties of a low temperature co-fired ceramic (LTCC) ferrite in the microwave range have been determined by performing S-parameter measurements of a coplanar waveguide (CPW) cell. An optimization procedure is used to minimize an error function that compares the measured S-parameters to those obtained from electromagnetic simulations based on the spectral domain approach (SDA) method in the saturated state. Using this method, the μ and κ parameters of the permeability tensor are extracted. Other results in the demagnetized and partially magnetized states show a special LTCC-ferrite behavior.
