Characterization of Magnetic Materials in the Millimeter-Wave Range (60-90 GHz) (Short Papers)

It is shown that the measurement techniques of dielectric samples using open resonators can also be used to characterize ferrimagnetic materials. The parameters that are measured are the complex permittivity epsilon/sub f/* and the Delta H ferrite gyromagnetic resonance Iinewidth. The principle of the techniques used and an evaluation of ferrite material parameters from 10 to 70 GHz are presented.
