Modulation of Mm-waves by an Acoustically Controlled Monocrystalline Hexagonal Ferrite Resonator
Modulation of mm waves with RF signals can be accomplished using stable non-linear resonance effects in monocrystalline hexagonal ferrite resonators (HFR), characterized by high crystallographic anisotropy. Acoustic oscillations excited in a piezoelectric slab having a good contact with the HFR can be used to control the HFR ferromagnetic resonance frequency. The design ideas of a modulator based on an HFR-piezoelectric slab structure are considered. Some experimental and calculation results are presented.
