Giant enhancement of the controllable in-plane anisotropy of biased isotropic noncentrosymmetric materials with epsilon-negative multilayers

Valagiannopoulos, Constantinos; Tsitsas, N. L.; Lakhtakia, A. (Journal of Applied Physics, 2017)

Giant in-plane anisotropy can be exhibited by a finitely thick periodic multilayer comprising bilayers of an isotropic noncentrosymmetric material and a non-dissipative isotropic medium of negative permittivity, when a ...
Mitigating Snell’s-Law Reflection and Transmission with Metasurfaces of Ordinary Dielectrics

Tsitsas, N. L.; Valagiannopoulos, Constantinos (IEEE, 2017)

Obtaining anomalous reflection and transmission (namely propagation along directions different from those predicted by Snell’s law) is investigated for plane waves impinging on a planar periodic metasurface composed of two ...
