Abstract

We present a highly-reconfigurable metasurface with unprecedented efficiency for spatial and spectral manipulation of optical wavefronts, leveraging control over the overlapped Mie-dipolar-modes of dielectric nanorings and large refractive index tunability granted by GeSbTe phase-change material.
