Alessandro Ciattoni,Carlo Rizza,Andrea Marini,Andrea Di Falco,Daniele Faccio,Michael Scalora +5 more
TL;DR: A.C. and C.R. as discussed by the authors acknowledge support from U.S. Army International Technology Center Atlantic for financial support (Grant No. W911NF-14-1-0315).
One-dimensional chirality: strong optical activity in epsilon-near-zero metamaterials
TL;DR: It is suggested that electromagnetic chirality, generally displayed by 3D or 2D complex chiral structures, can occur in 1D patterned composites whose components are achiral.
Transmissivity directional hysteresis of a nonlinear metamaterial slab with very small linear permittivity
TL;DR: In this paper, the authors investigated the propagation of a transverse magnetic field through a nonlinear metamaterial slab of subwavelength thickness and with a very small and negative linear dielectric permittivity.

Terahertz active spatial filtering through optically tunable hyperbolic metamaterials
TL;DR: In this article, the authors theoretically considered infrared-driven hyperbolic metamaterials able to spatially filter terahertz (THz) radiation, and numerically proved the device functionality by resorting to full wave simulation coupled to the dynamics of charge carried photoexcited by infrared radiation in semiconductor layers.

Gain assisted nanocomposite multilayers with near zero permittivity modulus at visible frequencies
TL;DR: In this article, a nano-laminate was fabricated by alternating metal and gain medium layers, the gain dielectric consisting of a polymer incorporating optically pumped dye molecules, and the real and the imaginary parts of the permittivity reached very small values.
