Magnetostatic Wave Spectroscopy

1994
In previous chapters we dealt with basic questions of the theory of the MSW excitation and propagation, in the case of their linear as well as nonlinear excitation. In this and the following chapters we will concentrate on experimental issues with regard to the practical application of the theoretical knowledge obtained, partly from the point of view ...

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 ...

Magnetostatic Waves, Microwave SAW?

1980 Ultrasonics Symposium, 1980
The continual demand for increased performance in modern communication and rader systems in terms of increased bandwidths and higher operating frequencies has led to investigation of novel techniques and technologies for analog signal processing. In particular, surface acoustic waves (SAW) have been extensively e xploited with great success to this end,

Magnetostatic wave oscillator frequencies

Journal of Applied Physics, 1981
The frequencies of magnetostatic wave (MSW) oscillators employing three principal modes of propagation, surface (MSSW), forward (MSFVW), and backward (MSBVW) volume waves, have been investigated. Previous (MSW) oscillator papers dealt with MSSW. Oscillators were fabricated using LPE-YIG MSW delay lines in a feedback loop of a 2–4 GHz amplifier.

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.

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 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 ...

Quasioptics of Magnetostatic Waves

1994
As a result of a large deceleration, magnetostatic waves are characterized by a relatively small wavelength in comparison with the wavelength of electromagnetic waves of the same frequency in vacuum. In typical cases in thin YIG layers the wavelength of magnetostatic waves (MSW) is from one to a hundred micrometres, i.e.

Magnetostatic wave interdigital transducers

Journal of Applied Physics, 1978
The design and operation of a novel type of magnetostatic wave transducer is described. The transducer is formed from an interdigital arrangement of narrow, open circuited microstrip fingers, each half an electromagnetic wavelength long. Experimental results in the frequency range 9–9.4 GHz are presented for 2, 4 and 10 finger transducers which are in ...

Anisotropy of Magnetostatic Waves

1994
In Chapter 1 magnetostatic waves propagating in a three-dimensional coordinate system (x, y, z) only in the x-axis direction were investigated. In this case the magnetic field could be oriented in the y-axis direction (forward volume waves), in the z-axis direction (surface MSW), and in the x-axis direction (backward volume MSW) (Fig. 2.1,.
