Dispersive-mode characterization of ferrite microwave circuits with arbitrary DC magnetic field polarization

This paper deals with the hybrid-mode analysis of the magnetic anisotropy in multilayered passive ferrite circuits. Based on the spectral domain approach (SDA), the proposed technique takes into account the arbitrary polarization of the static magnetic field. An original transition matrix was introduced to simplify the evaluation of electromagnetic fields in all dielectric layers leading to much faster computation time. Dyadic Green's functions were also deduced for ferrite materials with non-diagonal μ tensors. Numerical results are in good agreement with those available in the literature.
