Abstract :
The correlation of magnetostatic wave pulses in yttrium-iron garnet (YIG) films was investigated theoretically and experimentally. This method allows observing the signals below the noise level in a wide frequency band. An additional pumping pulse is proposed to use for the creation of time inverted reference signal, for the correlation of delayed direct and reversal by pumping signal pulses.
