Abstract

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 M1 metastructures (as a beam splitter) and M2 (in a shorted h-arm as a Fabry-Perot resonator reflector) controlled by independently by different methods: M1 – fiber-optically and M2 – electrically. The functional capabilities of a meta-interferometer with M1, containing a grating of parallel resonant dipoles with an orthogonally asymmetrically arranged copper strip (a CdS semiconductor plate in a gap), and with different M2 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 M1 responses (amplitude band transformation) and M2 (frequency transformation).
