Operation of the Galvanogyromagnetic Microwave Power Flow Detectors in a Frequency Range

The theoretical and experimental investigations of the galvanogyromagnetic microwave power flow detectors based on ferromagnetic films which are placed in unmatched waveguide has been made in this paper. It is shown, that there are two opposite sign maximum in the output signal of detector retuning by internal magnetic field. The sum of this extremal magnitudes is proportional to the active microwave power passing through the unmatched waveguide. The experimental results of the operation of galvanogyromagnetic detectors in S-band in unmatched waveguide with VSWR equal 3 and 9 are given.
