Due to the long wavelength of THz rays,conventional scaling of LC devices from the visible tothe THz range results in thicker devices with theunderlying disadvantages. A further option to overcomethese drawbacks is to use metamaterials.In this study, an active fishnet metamaterial based onhigh birefringence liquid crystal materials, is proposedand theoretically analyzed. Low absorption and lowrefractive index substrates (HDPE) coated with thicklayers of ITO (acting as a reflective layer at THz) areused. Apart from providing the electromagneticresonances that lead to negative refractive index, theITO layers also serve as the electrodes for theapplication of the control voltage. The latter allows forthe tuning of the metamaterial key parameters, suchas transmittance and effective permittivity orpermeability.2engLiquid crystalsMetasurfacesMetamaterialsTerahertz wavesThz wavesActive metasurface at THz based on liquid crystalsActive metasurface at terahertz based on liquid crystalsconference posterElectrónicaÓpticaopen accessCC/0000030055
