CPW magnetostatic wave band stop resonators

2005 European Microwave Conference, 2005
A frequency tunable magnetostatic wave (MSW) straight edge resonator (SER) made by a yttrium iron garnet (YIG) film has been used as a selective frequency component in a resonating filter. MSW CPW (coplanar waveguide) transducers on silicon wafers and S-parameters have been measured at different DC magnetic bias fields, with a frequency tunability ...

Electrodynamics of Magnetostatic Waves

1994
The widely used method of setting up the dispersion equations, i.e. the equations relating the wave number and frequency, for magnetostatic waves in space-bounded stratified structures is based on “sewing together” of the tangential high-frequency components of magnetic field intensity h x and normal components of magnetic induction by on the ...

Micromachined magnetostatic wave band-stop resonator

Proceedings. International Semiconductor Conference, 2003
A band-stop resonator on silicon wafer with a micromachined silicon membrane is presented in this paper. As a selective frequency component, a frequency tunable magnetostatic wave (MSW) straight edge resonator (SER), made of a YIG film, has been used. Frequency tunability ranged between 4.5 GHz-7.5 GHz for different DC magnetic biasing fields.

Wave front reversal of surface magnetostatic waves

Journal of Magnetism and Magnetic Materials, 2006
Abstract The wave front reversal (WFR) of non-reciprocal waves has been investigated. The experiment was performed using surface magnetostatic waves (SMSW) excited by a pulsed microwave signal of the carrier frequency ∼4.7 GHz in an epitaxial yttrium–iron garnet (YIG) film. The WFR was realized by pulsed parametric pumping of a double frequency. It

Magnetostatic Wave Frequency Selective Limiters

IEEE Transactions on Magnetics, 2013
Frequency selective limiters (FSLs), which selectively attenuate above threshold signals while allowing low power signals to pass with little attenuation, have potential application in maintaining the dynamic range of RF receivers in the presence of interference.

Magnons, magnetic polaritons, magnetostatic waves

Physics-Uspekhi, 1997
Electrodynamical properties of magnetically ordered media are analyzed theoretically. Two types of magnetic materials, namely ferromagnets and antiferromagnets, are considered and the effect of the magnetic subsystem on the properties of the host metal are discussed.

Propagation characteristics of magnetostatic waves

Circuits, Systems, and Signal Processing, 1985
The present paper reviews the propagation characteristics of the three magnetostatic wave-types that can exist in a ferrimagnetic film such as the commonly used epitaxial yttrium-iron-garnet (YIG) film, viz., magnetostatic surface waves (MSSWs), magnetostatic forward volume waves (MSFVWs) and magnetostatic backward volume waves (MSBVWs). The pronounced

Magnetostatic wave resonators and oscillators

Circuits, Systems, and Signal Processing, 1985
The purpose of this paper is to describe the current status of magnetostatic wave tunable resonators operating between 2 and 12GHz and their applications to microwave oscillators, the wave propagating in a pure yttrium-iron-garnet epi-layer. The first section deals with magnetostatic surface wave (MSSW) resonators consisting of a pair of reflective ...

Magnetostatic Volume Wave Resonators

MTT-S International Microwave Symposium Digest, 2005
The purpose of this paper is to report new advances about magnetostatic volume wave (MSVW) resonators. The waves have been propagated in an epitaxial yttrium iron garnet (YIG) film at GHz frequencies. These devices use periodic etched groove gratings as distributed reflectors for MSVW.

Magnetostatic Wave Reflective Array Filter

MTT-S International Microwave Symposium Digest, 2005
Results from experimental and theoretical studies, carried out in the 3 GHz region in epitaxial YIG, on tunable magnetostatic forward volume wave (MSFVW) oblique Incidence reflective array filters are reported. Uniform reflecting gratings consisting of either metal bars or metal dot arrays have been studied as MSFVW reflectors and yield an octave ...
