Millimeter wave signals detection by means of monocrystal hexagonal ferrite ellipsoid

Stable nonlinear resonance effects (SNLREs) have been already studied in crystallographically ´isotropic´ ferrogarnet ferrite resonators (FR), employed as microwave detectors in the frequency range of 300 MHz to 30 GHz. Application of prospective hexagonal monocrystal ferrites with large field of crystallographic magnetic anisotropy leads to the possibility of a gyromagnetic converter (GC) design for mm waveband (from 30 to 200 GHz) without massive external magnets. This paper deals with the analysis of a more general case with taking into account both crystallographic and form anisotropy as well as the arbitrary orientation of the main crystallographic axis with respect to the constant field of external magnetization
