Modulation of Mm-waves by an Acoustically Controlled Monocrystalline Hexagonal Ferrite Resonator
نویسنده
چکیده
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.

Frequency-selective Power Transducers “Hexagonal Ferrite Resonator—Semiconductor Element”
The transducers studied herein allow for frequency-selective measurement of mm-wave power parameters. Frequency selectivity is assured by a monocrystalline hexagonal ferrite resonator (HFR). The HFR is in direct contact with a semiconductor element (SE)—an unpackaged Hall-element, or a chip transistor (or diode). Power absorbed by the HFR at the ferromagnetic resonance converts to heat, and the...

متن کاملMicrowave and MM-wave magnetoelectric interactions in ferrite-ferroelectric bilayers
Measurements of the strength of magnetoelectric (ME) interactions at microwave and millimeterwave frequencies have been carried out on layered ferrite-piezoelectric oxides. An electric field E applied to the composite produces a mechanical deformation, resulting in a field shift δHE or a frequency shift δfE in the resonance. A stripline structure or a cavity resonator was used. The strength of ...
متن کاملThe field symmetry breaking effects in microwave-vortex structures originated by ferrite disks in a cavity
For a microwave resonator with an enclosed ferrite disk, one has the electromagnetic resonant fields which are not the fields of standing waves. This leads to very specific topological-phase characteristics. In such a nonintegrable system with time-reversal symmetry breaking, one obtains the Poynting-vector microwave vortices and intensive field localization in a region of a disk. The purpose o...
متن کاملChiral states of electromagnetic fields originated from ferrite-based microwave vortices
Electromagnetic vortices in a microwave cavity with an inserted piece of a magnetized ferrite appear due to the time-reversal symmetry breaking effect. We reveal numerically that the Poynting-vector vortices are possible in open resonant microwave structures with ferrite inclusions. We demonstrate a pair of resonances which have opposite vortex rotations at the same direction of time given by t...
