All-dielectric metasurfaces for terahertz science and technology

All-dielectric metasurfaces are useful for investigation of new devices for terahertz science and technology. Scattering effects ranging from high absorption and Huygens' reflect arrays to bound-states-in-the-continuum (BIC) suggest their use for applications. We experimentally demonstrate several all-dielectric metasurfaces which realize: high transmission Huygens’ structures, high absorptive devices for imaging, and dynamic surfaces with optical control. The all-dielectric metasurfaces we explore consists of arrays of high dielectric geometrical shapes, and may support a number of eigenmodes of either odd or even symmetry.
