Magnetostatic wave terminations
Journal of Applied Physics, 1978Magnetostatic waves (MSW) propagating in low line-width (ΔH<0.5 Oe) yttrium iron garnet (YIG) films grown by liquid phase epitaxy (LPE) constitute a potential basis for analog signal processing directly at microwave frequencies (1–20 GHz). MSW device techniques are complementary to those utilized in surface acoustic wave (SAW) devices at VHF/UHF.

Japanese Journal of Applied Physics, 1988
This paper describes a voltage-controlled oscillator with low SSB (single side band) phase noise using an MSW (magnetostatic wave) device. There is a discussion on what is involved in eliminating the SSB phase noise. An MSW oscillator is tested and the SSB phase noise is measured to be -115 dBc/Hz at 10 kHz offset with a oscillation frequency of 2.0

Circuits, Systems, and Signal Processing, 1985
The present paper reviews recent theoretical results, and reports initial experimental results, on the convolution of contra-propagating magnetostatic forward volume waves (MSFVWs), in the form of cw signals or time-limited cw pulses, in an epitaxial yttrium iron garnet (YIG) film.

Microwave magnetostatic wave coupled resonators
Journal of Magnetism and Magnetic Materials, 1996Abstract In this work the microwave response of an integrated structure composed of coupled magnetostatic wave (MSW) straight edge resonators (SER) based on an epitaxial yttrium iron garnet film and measured by means of a ferromagnetic resonance (FMR) experiment has been studied.

Power Handling Of Magnetostatic Wave Resonators
1997 IEEE International Magnetics Conference (INTERMAG'97), 1997In this paper, an experiment is presented to study a possible power handling enhancement of magnetostatic forward volume wave straight edge resonators. Theoretically, the power range for a linear response of the resonator is expected to be increased by inclining the sample with respect to the dc magnetic bias field direction, and a critical angle can ...

CPW Cascaded Magnetostatic Wave Band Stop Resonators
INTERMAG 2006 - IEEE International Magnetics Conference, 2006Magnetostatic-wave resonators in bandstop configuration have been studied by using a coplanar waveguide transmission line to excite the resonating signal. The microwave performances of such a device have been discussed and implemented by using cascaded resonators, to improve the micro wave absorption and the selectivity response of the entire structure.

Magnetostatic Wave Signal Processing
1977 Ultrasonics Symposium, 1977A novel technology for analog, real time, signal processing at GHz frequencies is described utilizing the propagation of slow magnetostatic waves in magnetically biased films of yttrium iron garnet, grown by liquid phase epitaxy on substrates of gadolinium gallium garnet.

Magnetostatic wave notch filter
1992 IEEE Microwave Symposium Digest MTT-S, 2003The application of epitaxial YIG resonators in a tunable notch filter design with a center frequency of 9 GHz is reported. Tuning from 8 to 19 GHz was accomplished via a miniature electromagnet with a volume of about 1 cm/sup 3/. This volume gives the filter application in phased arrays of simultaneous transmit/receive antenna modules. >
