Effect of Resonance Responses of Spatially Separated and Independently Electrically Controlled Metastmctures with Varactors on Microwave Interferogram of Meta-Interferometer

摘要

Application of spatially separated and independently electrically controlled from different sources resonant metastructures is proposed for control of a multiband interferogram of a meta-interferometer. Independent control of the frequency and width of the stopband in an interval of 3-6 GHz is demonstrated for the M1 metastructure (that serves as a beam splitter) containing a periodic grating of parallel wires with an orthogonally asymmetrically located copper strip with a break loaded with a varactor and the M2 metastructure (in a shorted h-arm that represents a double-split dipole ring with two varactors. The resonance responses of the metastructures and the dynamics of the interferogram are studied versus the reverse bias voltage across the varactors.
