- Abstract
- We suggest all dielectric metasurfaces composed of silicon (Si) nanoblock array. We can control the phase and polarization of light reflected the metasurface by changing Mie scattering of each Si block. The Mie scattering is easily adjusted by changing structure parameters of Si block width and height. In single Si nanoblock, the magnetic dipole resonance mode was diminished when decreasing its height. In this study, for making 2-dimensional metasurface, we analyze the scattering cross-section by changing width and height of Si nanoblock with finite-difference time-domain method.
