Low-loss and lossy optical metasurfaces based on ellipsoidal nanoparticles

Abstract

In this contribution, we describe the optical properties of bi-dimensional arrays of ellipsoidal nanoparticles and propose some potential applications. First, we analyze a 2D metasurface model able to rigorously characterize the optical behavior of these structures in terms of equivalent surface impedance. Then, we comment some of their possible applications ranging from the design of optical scattering cancellation devices up to the realization of transparent screens. Full-wave simulations are provided to confirm the effectiveness of the analytical model.
