Interaction of microwave signals in a resonance transmission line based on magnetostatic waves

Interaction between two (small and large) regular microwave signals that simultaneously pass through a resonance transmission line based on backward volume magnetostatic waves is studied experimentally in different frequency ranges. It is found that the amplitude-frequency response of the small signal near the frequency of the large one depends on the frequency of the latter; namely, the amplitude of the small signal is affected by spin-wave packets parametrically excited by magnetostatic and electromagnetic pumps.
