Аннотация доклада:
Optical properties of phase-change materials (PCM) GeTe and GeTe2 were studied. Active planar metamaterials based on PCM with ultrafast switching of THz field characteristics were developed. A new technique for obtaining the complex refractive index of metamaterials based on simultaneous measurement of reflection and transmission of THz radiation was proposed and experimentally confirmed. Such anisotropic effects as optical activity and circular dichroism in the interaction of THz field with active metamaterials were investigated.
