Active KTaO3 hybrid terahertz metamaterial [PDF]
Scientific Reports, 2017 AbstractThe dielectric properties of an active KTaO3 hybrid metamaterial structure and its tunability under external electric fields are investigated at room temperature by means of terahertz time-domain spectroscopy. Application of the electric field leads to an appreciable tuning of the dielectric loss, which is up to 17%.

Double‐Sided Metamaterial for Sensitivity Enhancement in THz Impedance Spectroscopy
Laser &Photonics Reviews, EarlyView.Identical double‐sided THz MM sensor is described, which has high resonance strength and quality along with enhanced dielectric response due to enhanced THz blocking and light‐trapping effects. Applying FP‐MM resonance de‐coupling techniques, this architecture reaches a sensitivity of 1400 GHz/RIU. Abstract Multi‐layer terahertz (THz) electric‐LC (ELC)
