It is suggested that it should be possible to make low insertion loss devices (e.g., Faraday rotators, phase shifters, and broad-band filters) to operate in the millimeter wave range using a multilayer array of thin films magnetized perpendicular to the films with waves of frequency below the magnon continuum normally incident.

The dispersion characteristics of microstrip lines on magnetically anisotropic substrates are studied utilizing the Galerkin's method in the spectral domain. Specifically, we calculate the differential phase shifts of devices consisting of Z-type (Zn₂Z) and Y-type (Zn₂Y) ferrites as a function of applied magnetic field. Our theoretical formulism is effective in modeling highly magnetically anisotropic materials, which are becoming increasingly important for the next generation of microwave devices. Such a theoretical treatment of anisotropic ferrite magnetic materials is presently unavailable in commercial numerical simulation tools.
