Abstract: Abstract The active controllable metasurfaces based on electromagnetically induced transparency (EIT) have attracted great interest in the research of terahertz functional devices. We demonstrate a dual-mode controllable terahertz metasurface based on complementary plasmon-induced reflection structure.… read more here.
