Energy eigenstates of magnetostatic waves and oscillations

Physical Review E, 2001
Effect of excitation of magnetostatic oscillations in a ferrite resonator by the microwave magnetic field was a subject of many publications of more than the last 40 years. The most interesting multiresonance spectrum of absorption peaks one can observe experimentally is a case of disk-form small ferrite resonators.

Magnetostatic Wave Signal Processing

IETE Technical Review, 1987
Magnetostatic waves propagating in thin YIG-films grown by liquid phase epitaxy on GGG (Gadolinium Gallium Garnet) substrates under proper magnetic biasing have proven capabilities for analog, real time signal processing at microwave frequencies. The state-of-the-art of MSW for signal processing has been reviewed with special emphasis on delay lines ...

Magnetostatic spin waves in nanoelements

Physica B: Condensed Matter, 2004
Abstract The relaxation of magnetostatic spin waves in a square NiFe nano-element (100×100×20 nm3) has been simulated by micromagnetic finite element modeling after the excitation by a rotational field of μ0H=0.2 T with various frequencies between 1 and 16 GHz.

Magnetostatic Wave Signal Processing

1977 Ultrasonics Symposium, 1977
A 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.

Compact Magnetostatic Wave Channelizer

MTT-S International Microwave Symposium Digest, 2005
A compact 5 channel filter bank is described which uses the new technology of magnetostatic forward volume waves propagating in narrow epitaxial yttrium iron garnet strips. Results are presented showing S-band performance where a -55 dB out-of-band level is achieved and a 2 tone intermodulation level rejection of 50 dB at 25 MHz from the mid-band ...

Indicatrices of magnetostatic surface waves

Bulletin of the Russian Academy of Sciences: Physics, 2017
Indicatrices (isofrequency curves) of magnetostatic surface waves are studied with allowance for wave attenuation. A bias magnetic field is applied tangentially to a ferrite film. Arbitrary angles between the bias magnetic field and the wave vector are examined.

Magnetostatic Surface-Wave Transducers

IEEE Transactions on Microwave Theory and Techniques, 1979
Magnetostatic surface-wave (MSSW) transducer theory is extended and generalized. A Fourier transform relation is established between MSSW field amplitudes and transducer spatial current distribution. Expressions are developed for the radiation resistance of periodic meander and grating transducers, spatial harmonic amplitudes, and radiation resistance ...

Magnetostatic Wave Compressive Receiver

MTT-S International Microwave Symposium Digest, 2005
An S-band compressive receiver if utilizing an MSW (Magneto-stetic Wave) epitaxial YIG dispersive delay line for broadband spectral analysis is presented. The dispersive line, centered at 2.7 GHz with an 870 GHz bandwidth dispered over 0.2 MSCC allows analysis of a 650 GHz band with 12 MHz resolution.

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

Nonlinear Properties of Magnetostatic Waves

1994
Up to now linear processes in ferromagnetic media have been investigated, i.e. processes at very small amplitudes of external high-frequency field \( \vec{h} \) and at time-dependent magnetization \( m \). The Landau-Lifshitz equation for the vector of magnetization (1.21) is in the general case nonlinear. It was linearized using the assumptions $$
