Abstract

ince many applications rely on the knowledge of the electromagnetic
material properties of ferrites, such as ferrite phase shifters, this paper
presents an algorithm for characterizing ferrite materials in a single
frequency using a rectangular waveguide system. In this method, the
extraction of ferrite parameters is implemented through minimizing the
difference between the measured data and the results from modal
analysis of the system. The main advantage of this method compared to
the other ones is that the proposed method only needs the amplitude of
the reflection and transmission coefficients to estimate the parameters of
ferrite materials. This makes the implementation easy and eliminates the
problems associated with phase calibrations and measurements. This
validation is achieved by simulation and experimental tests. The
proposed algorithm is validated by characterizing YIG and SL-470
ferrites.
