A specific selective effect of ferromagnetic and dipole resonances on an interference pattern in the range of 3–6 GHz has been detected experimentally for the first time in a modified interferometer based on a waveguide T junction with a metastructure consisting of a ferrite plate and varactor-loaded dipole or ring conducting elements as a controlled beam splitter. A dependence of the shape, width, intensity, and frequency of an interference band on the magnitude and sign of a static magnetic field H, the relative position of ferromagnetic resonance and band, and the electric voltage VDC on varactor diodes has been observed. The nonreciprocity of microwave transmission in interference stop bands characterized by change in the transmission coefficient T at the inversion of H has been revealed. Nonreciprocity increases at the excitation of ferromagnetic resonance near a band. In this case, a jump of T by two orders of magnitude to a level of a passband is observed with the reversal of the magnetic field H. The sign of nonreciprocity depends on the relative position of ferromagnetic resonance and the stop band and can change at a small variation of the magnitude of H. The selectively controlled narrowing of the nonreciprocal band by several times, as well as the shift by 0.2 GHz, is observed with the variation of VDC in the range of 0–10 V.
