Abstract

We employ Phase-Change Materials (PCMs) for local addressing of individual meta-atoms in both metallic and low-loss dielectric metasurfaces, with special emphasis on tuning electric dipole (ED) and magnetic dipole (MD) resonances simultaneously or individually. Individual control of the electric and magnetic dipole resonances of split-ring resonators (SRRs) is demonstrated by locally changing the refractive index of aluminum SRRs in the corresponding hotspots of the antenna resonances and by direct writing and reconfiguration of SRRs in the new plasmonic PCM In3SbTe2.
