| Popis: | A concept of an efficient ultrathin spatial phase modulator for correcting terahertz wavefronts in transmission with subwavelength spatial resolution is experimentally demonstrated. It exploits a combination of spatially addressable resonant planar metamaterials (so-called metasurfaces) and an optically thin ( |
