Abstract

This paper presents the application of the magneto-optical method for the first time in the millimeter wave range for the characterization of ferrites. The magneto-optical measurements were realized with a specially built millimeter wave spectrometer. Backward wave oscillators were used as a source of tunable coherent radiation. It is demonstrated that this new method is capable of generating accurate millimeter wave dielectric and magnetic data for any type of ferrite material.
