Fabry-Perot resonances in planar terahertz metamaterial structures have been investigated both theoretically and experimentally. It has been demonstrated that performance of frequency-agile metamaterial modulator can be optimized by adjustment of dielectric substrate thickness in accordance with operating frequency of metamaterial.
Optically controlled mode switching in the split-ring resonators deposited on the lattice-matched InGaAs/InP was demonstrated at excitation wavelengths 900-1200 nm. Using tunable excitation wavelength as well as split-ring resonators of different configurations attempts were made to optimize the mode switching conditions for application of tunable(More)
In this work, we investigate the transmission properties of planar arrays of split-ring resonators formed on the surface of a dielectric plate. The modulation concept is demonstrated by using several metamaterial structures with a different effective capacitance of the split gap, thus imitating a metamaterial of tunable frequency. The proposed modulation(More)
