The array of Josephson junctions (JJ) was integrated into SWR. The total Josephson jumps for an array of 4 - 200 parralel junctions were measured. The radiation of JJ array in SWR was registrated. The interaction spin waves (SW) with spatially localised impulse electromagnetic radiation was investigated. The nonadaibatic regime of parametric interaction of SW was realized. Compression of amplified pulses were reached by using localized nonstationary pumping, which makes possible to obtain high amplification gains of SW envelope soliton (17 dB). The theory of SW interaction with spatially localized parametric pumping was developed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
