2. Lecture at CAS-2020 – Analytical and Computational Study of Phase-Controlling of Metasurfaces , authors : S. Iftimie, A. Radu, D. Dragoman.

In this study, we present computational results of phase-controlling of an architecture containing gold meta-atoms on top of a silicon dioxide dielectric layer, grounded or not with a bottom metallic layer. We have demonstrated that the proposed metasurface can operate as a lens, and the spectral dependence of R, T, and A for both grounded and not grounded structures is independent of the rotation angle of the meta-atoms
