Abstract :
A new active magnetostatic wave (MSW) delay line based on the parametric interaction of MSW wave packets with electromagnetic pumping has been developed and tested. The time delay and amplitude of the output delayed pulsed signal are controlled by the amplitude, duration, and the moment of application of the pumping pulse. The proposed delay line is dispersionless. The amplitude of the output delayed pulse can be kept constant in the whole interval of possible time delays and can be made larger than the amplitude of the input pulse.
