ABSTRACT:
The invention relates to tunable selective devices based on magnetostatic volume waves and has as its object to provide a device comprising two resonator networks arranged to exchange magnetostatic volume waves via a selective return reflector network, in which the reflector network is devised so as to eliminate the longitudinal intereference modes present around the required longitudinal mode. The invention is applicable in particular to the filtering of electrical signals at very high frequency, to the production of tunable oscillators and to the measurement of magnetic fields.
