Аннотация

First it has been observed that microwave interferometer with embedded metastructure, meta-surface or meta-atom as voltage-controlled original beam-splitter can show new functionalities, such as specific selective control of line width and intensity, as well line shape and position in multiband spectral filtering. We realize and investigate modified meta-interferometer on basis of rectangular waveguide tee with varactor-loaded conductive resonance elements as a beam splitter at 3 – 6 GHz. It is achieved tunable considerable narrowing and 0.15 – 0.2 GHz shifting of band; switching between stop-band (-25 dB) and pass-band (-2;-5 dB), as well widening and intensification of each filtering band by turns in dependence on resonance element properties and bias voltage 0 – 10 V. The results open up a new approach to implement switchable and tunable multiband microwave filters.
