Anomalous reflection of visible light by all-dielectric gradient metasurfaces

Tsitsas, Nikolaos L.; Valagiannopoulos, Constantinos (Journal of the Optical Society of America B, 2017-03-15)

Plane wave scattering by a planar metasurface composed of two periodically alternating rectangular dielectric rods is considered. A rigorous integral equation methodology is employed for the analysis and the accurate ...
Chimera states and synchronization in magnetically driven SQUID metamaterials

Hizanidis, J.; Lazarides, N.; Neofotistos, G.; Tsironis, G. P. (European Physical Journal: Special Topics, 2016-09-01)

One-dimensional arrays of Superconducting QUantum Interference Devices (SQUIDs) form magnetic metamaterials exhibiting extraordinary properties, including tunability, dynamic multistability, negative magnetic permeability, ...
Parity-Time Symmetric Nonlocal Metasurfaces: All-Angle Negative Refraction and Volumetric Imaging

Monticone, Francesco; Valagiannopoulos, Constantinos; Alù, Andrea (American Physical Society. Physical Review X, 2016)

Lens design for focusing and imaging has been optimized through centuries of developments; however, conventional lenses, even in their most ideal realizations, still suffer from fundamental limitations, such as limits ...
