چکیده
We report on the design, fabrication, and characterization of compact tunable yttrium iron garnet (YIG)-based RF resonators based ?m-sized spin-wave cavities. Inductive antennas with both ladder meander configurations were used as transducers between spin waves signals. The excitation ferromagnetic resonance standing in YIG cavities led to sharp resonances quality factors up 350. observed spectra excellent agreement a model dispersion relations YIG, showing high magnetic field tunability about 29 MHz/mT.

Electrodynamic study of YIG filters and resonators
Numerical solutions of coupled Maxwell and Landau-Lifshitz-Gilbert equations for a magnetized yttrium iron garnet (YIG) sphere acting as a one-stage filter are presented. The filter is analysed using finite-difference time-domain technique. Contrary to the state of the art, the study shows that the maximum electromagnetic power transmission through the YIG filter occurs at the frequency of the ...
متن کاملHigh-Q Tunable Microwave Cavity Resonators and Filters using SOI-based RF MEMS Tuners
This paper presents the modeling, design, fabrication and measurement of MEMS-enabled continuously tunable evanescent-mode electromagnetic cavity resonators and filters with very high unloaded quality factors (Qu). Integrated electrostatically-actuated thin diaphragms are used for the first time for tuning the frequency of the resonators/filters. An example tunable resonator with 2.6:1 (5.0 − 1...
متن کاملTunable resonators for quantum circuits
We have designed, fabricated and measured high-Q λ/2 coplanar waveguide microwave resonators whose resonance frequency is made tunable with magnetic field by inserting a DC-SQUID array (including 1 or 7 SQUIDs) inside. Their tunability range is 30% of the zero field frequency. Their quality factor reaches up to 3×10. We present a model based on thermal fluctuations that accounts for the dependa...
متن کاملElectrostatic fringing-field actuation for pull-in free RF-MEMS analogue tunable resonators
This paper presents the design, fabrication and measurement of the first pull-in free tunable evanescent-mode microwave resonator based on arrays of electrostatically actuated fringing-field RF-MEMS tuners. Electrostatic fringing-field actuation (EFFA) is the key on achieving a wide tunable frequency range that is not limited by the conventional pull-in instability. Furthermore, total lack of d...

Electrically coupled, high quality factor (Q), tunable channel-select ladder filters comprised of dielectrically transduced thickness shear mode esonators are presented using integrated circuit compatible bulk micromachining technology. The filters are fabricated on the 3.2 m thick device ayer of heavily doped SOI wafers with a 20 nm thick hafnium dioxide film sandwiched between the polysilicon...
