Spectral-domain modeling of anisotropy in ferrite microwave circuits with multilayer configuration

This paper deals with the analysis of anisotropy effects on the dispersion parameters of multilayer microwave circuits with ferrite substrates. Since ferrites present a biaxial anisotropy, spectral analysis of multilayered configurations with such substrates is not generalized yet but restricted to some particular cases of tensors. The proposed general analysis was carried out by the spectral domain approach method (S.D.A) and takes into account for the first time the electrical aspect of anisotropy. The computed results are in good agreement with those available in the literature.
