PT-Symmetric planar devices for field transformation and imaging

Valagiannopoulos, Constantinos; Monticone, F.; Alù, A. (2016)

The powerful tools of transformation optics (TO) allow an effective distortion of a region of space by carefully engineering the material inhomogeneity and anisotropy, and have been successfully applied in recent years ...
Robust chimera states in SQUID metamaterials with local interactions

Hizanidis, J.; Lazarides, N.; Tsironis, G. P. (Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2016-09-27)

We report on the emergence of robust multiclustered chimera states in a dissipative-driven system of symmetrically and locally coupled identical superconducting quantum interference device (SQUID) oscillators. The "snakelike" ...
Wide-angle absorption of visible light from simple bilayers

PAPADIMOPOULOS, ATHANASIOS N.; KANTARTZIS, NIKOLAOS V.; TSITSAS, NIKOLAOS L.; Valagiannopoulos, Constantinos (Optical Society of America, 2017-12-08)

Color-selective absorption of light is a very significant operation used in numerous applications, from photonic sensing and switching to optical signal modulation and energy harnessing. We demonstrate angle-insensitive ...
