Paper Abstract

In this work, we combine the plasmonic material with high index dielectric to design a metasurface. With the dyadic Green function and coupled-dipole approach, a Huygens’ metasurface is obtained by two dimensional array of subwavelength Ag core-Si shell nanoparticles, the transmission efficiency is close to unity in a broadband spectrum, and the reflection is completely eliminated by spectrally overlapping the magnetic dipole resonance with the electric dipole resonance. The designed high transmitted Huygens’ metasurface can be applied to wavefront shaping and beam forming.
