Spatially Spaced the Meta-Interferometer Contains Metastructures Controlled Independently by Different Methods: Optical and Electrical

For controlled multichannel multiband microwave filtering and effective decoupling between signal and control channels and between control channels, a proposed and experimentally investigated meta-interferometer with spatially spaced 1 metastructures (as a beam splitter) and 2 (in a shorted -arm as a Fabry-Perot resonator reflector) controlled by independently by different methods: 1 — fiber-optically and 2 — electrically. The functional capabilities of a meta-interferometer with 1, containing a grating of parallel resonant dipoles with an orthogonally asymmetrically arranged copper strip (a CdS semiconductor plate in a gap), and with different 2 are shown: a butterfly dipole loaded with varactors and a dipole ring, as well as a grating with copper strip (varactor in a gap). The possibility of independent control of individual interferogram exclusion bands in accordance with the effects of resonant 1 responses (amplitude band transformation) and 2 (frequency transformation).
