Your library or personal account may give you access

Abstract

We propose and experimentally demonstrate a dielectric metasurface for efficient beam-deflection with off-resonance near-unity transmittance in the visible wavelength. By reducing the supercell length, the beam deflection can switch efficiently, achieving beam-deflection of 16.50 degrees.
